With the limited power of the system, a large 13.7-m antenna was required to achieve the required sensitivity. The antenna was designed to be an extremely rigid structure, and great attention was placed on maintaining it at a uniform temperature, in order to achieve adequate surface tolerances on such a large dish.

With the advances in trajectory-extrapolation algorithms and calibration that have taken place, the millimeter-wave (MMW) radar acquires targets very reliably and achieves angle accuracy typical of a good optical telescope, approximately 40 мrad. Figure 17 is a photograph of the MMW radar antenna, taken as the radome was being installed. As expected, the MMW radar has become the premier imaging radar of the Kwajalein Missile Range and is heavily used by the SOI community. Its short wavelength effectively increases the number of scatterers visible on objects being observed and contributes to the superb detail of the images. Its ability to measure miss distance or impact point on intercepts is increasingly important to the BMD users. Additional details on the MMW radar and its uses appear in the previously mentioned article on wideband radars mmw radar The Millimeter Wave Radar The Millimeter Wave Radar, or MMW, was built at Kwajalein by Lincoln Laboratory (with significant contributions by the University of Massachusetts, RCA, and Raytheon) to extend the general imaging and tracking capabilities of ALCOR and to develop millimeter-wavelength signatures of ballistic missile components. The MMW, shown in Figure 5, became operational at Ka-band (35 GHz) in 1983, and Wband (95.48 GHz) in 1985, sharing a paraboloidal antenna with a diameter of forty-five feet. 13.5 metrow ############################# Both systems initially featured wideband waveforms of 1000- MHz spread generated by linear FM, and achieved 0.28-m range resolution. ################### The transmitted pulse width is 50 ¦Мsec at a maximum pulse-repetition rate of 2000 pulses per second.

milstar: Fire control The Pantsir-S1 fire control system includes a target acquisition radar and dual waveband tracking radar (designation 1RS2-1E for export models), which operates in the UHF and EHF waveband. ################################ Detection range is 32–36 km and tracking range is 24–28 km for a target with 2 m2 RCS.[4] This radar tracks both targets and the surface-to-air missile while in flight. As well as radar, the fire control system also has an electro-optic channel with long-wave thermal imager and infrared direction finder, including digital signal processing and automatic target tracking. A simplified, lower-cost version of Pantsir-S1 is also being developed for export, with only the electro-optic fire control system fitted. The two independent guidance channels - radar and electro-optic - allow two targets to be engaged simultaneously. Maximum engagement rate is up to 10 targets per minute. with the price per single unit being about US$ 15 million. Target acquisition radar: Type: phased-array Coverage: 360° Maximum detection range: at least 32 km, up to 36 km Band: UHF Target tracking radar: Type: phased-array Coverage: cone +/-45° Maximum tracking range: at least 24 km, up to 28 km Maximum number of targets can be tracked simultaneously: 20 Maximum number of targets can be engaged simultaneously: 3 Maximum number of missiles can be radio-controlled simultaneously: 4 Band: EHF IFF: Separate or integrated upon customer's request Autonomous Optoelectronic System: Type: Detection, automatic acquisition and tracking of air and ground targets Target tracking band: Infra Red 3-5 µm Missile localisation band: Infra Red 0,8-0,9 µm Maximum number of targets can be tracked simultaneously: 1 Maximum number of targets can be engaged simultaneously: 1 Maximum number of missiles can be localised simultaneously: 1 System: Number of targets that can be simultaneously engaged: 4 (three by radar, one by EO) Maximum number of targets engagement rate: 10 per minute Crew: 1 - 2 operators for the air defense system and 1 driver Reaction time: 4–6 seconds (from target acquisition to firing first missile) In May 2000, the United Arab Emirates ordered 50 Pantsyr-S1 systems, mounted on MAN SX 45 8Ч8 wheeled vehicles. The first batch was delivered in November 2004. However a new radar was requested by the UAE and first deliveries of the completed system took place in 2007. Final deliveries are scheduled for 2009. Syria has placed an order for 50 Pantsyr-S1 systems. Deliveries began in June 2008. Jordan has also placed an order for an undisclosed number of systems.

milstar: Dual-Band Radar (DBR) The DBR concept combines the detection capability of the SPY-3 system on the horizon and the VSR in the volume to efficiently respond to surveillance, track, threat assessment, and engagement support commands from the ship’s combat system. Coordinated resource management, scheduling and tracking provide potent functionality to provide quick reaction cued acquisition to threat targets, dual band counter to electronic attack, backup L-band horizon search coverage during X-band missile illumination support, and balancing of precision tracking radar resources. ######################################################################################### Control of each radar at the waveform level promotes a more optimized usage of both frequencies to maximize utilization of the radar timeline and increase search and track revisit rates. Correlation of detection measurements in a centralized track database provides for improved precision threat track, minimized fades and reduced susceptibility to electronic attack. The DBR concept also provides an excellent ATC capability for CV(X) operations; whereby, the VSR handles air traffic marshalling and the MFR supports precision landing. The Dual Band Radar (DBR) combines the functionality of the X-Band AN/SPY-3 Multi-Function Radar with that of an S-Band Volume Search Radar ############################################################################################# (VSR). X-band advantages include superior low-altitude propagation effects, narrow beam width for best tracking accuracy, widest frequency ######################################################################################### bandwidth for effective target discrimination and submarine periscope detection, and the necessary target illumination frequency for SM-2 and Evolved ################################################################################################ Seasparrow Missiles (ESSM). S-band advantages include a high-power aperture for effective search functionality, acceptable propagation loss regardless of weather, and sufficiently ################################################################################################# small beam width to resolve and track targets accurately. ##################################### Both bands are capable of providing effective uplink/ downlink capabilities to interface seamlessly with the ship’s surface-to-air missile systems. Operating simultaneously over two electromagnetic frequency ranges (X-band and S-band), the DBR marks the first time this functionality has been achieved using two frequencies coordinated by a single resource manager. As a result, the system delivers capabilities and flexibility not possible with earlier generations of land and maritime radar systems. ################################################################################### Many of the search and track functions can be allocated to either or both frequencies. Horizon search (to detect anti-ship cruise missiles) and precision track (to provide high update rate, fire control quality data) are examples. Since environmental phenomena affect different frequencies in different ways, the ability to bring both frequencies to bear increases performance during multipath and anomalous propagation. In addition, in situations where one band becomes taxed (such as when supporting multiple missiles in flight), the other band can effectively share the workload. As a class, phased array radar systems have done much to improve reliability, essentially by their absence of moving parts in the antenna. The DBR takes this to the next level: The active electronically steered arrays have been engineered to offer graceful degradation, thereby minimizing the possibility of systemwide or single-point failures. Built-in redundancy ensures system operability if radar component failures occur. The DBR is designed to operate 24/7 over a very long mission time at an operational availability better than 95%. The DBR contains a robust fault detection/fault isolation system, which notifies the ship system of any required maintenance. Replacement of components for the DBR arrays, subsystems, computers and other ancillary equipment typically involves swapping out circuit cards, solid state transmit/receive integrated multichannel modules (TRIMMS), or other modular components, all of which keep potential down time to a minimum. Access to all antenna components is from the rear, which will permit servicing from within the ship. The DBR is being designed to require fewer than 100 hours of corrective and preventive maintenance per mission-year and has a mean time to repair (MTTR) of less than 30 minutes. The DBR requires no dedicated operator and has no manned display consoles. The system automatically senses the complex man-made and natural environment and adjusts its processing accordingly. Specific tactical radar behavior is governed by doctrine, entered by a tactical action officer or sensor supervisor within the ship’s Total Ship Computing Environment (TSCE) or host command and control system. Being fully automated, the DBR takes the reaction time associated with manual operator action out of the loop and eliminates the potential for human error associated with manual radar settings. The only human interaction involves maintenance and repair activities, performed by technicians using a maintenance local area network (LAN) that allows them to take control of the radar and to run offline tests. The DBR is the first radar for which complex signal and data processing is done entirely in a Commercial-off-the-Shelf (COTS) computer. Computing products from IBM, Hewlett-Packard and Sun Microsystems all offer competitive, capable solutions. All DBR software has been designed using objectoriented techniques and is written in the widely used C++ and Java languages. DBR software is fully interoperable with the TSCE, an Open Architecture (OA) solution that integrates all of the ship’s computer functions into a single enterprise network. The TSCE also serves as a basis for the Navy standard combat system, designed for fleet-wide use. http://www.globalsecurity.org/military/systems/ship/systems/dbr.htm

milstar: In late 2008, details emerged of a new multiband 3D radar system in development by NNIIRT, designated the Nebo M. The Nebo M is a radical departure from previous Russian designs. The self-propelled Nebo M is a package of three discrete radars and a single processing and command van, all hosted on BZKT BAZ-6909-015 8 x 8 all terrain 24 tonne chassis, based on the same vehicle as the S-400 / SA-21 5P85TE2 TEL and the proposed wheeled SA-23 variant. The Nebo M combines derivatives of three existing NNIIRT 3D radars, the VHF band Nebo SVU, the L-band Protivnik G and the S/X-band Gamma S1. While the NNIIRT slide (below) attributes the VHF component to the 55Zh6 Tall Rack, the actual antenna design is clearly based on the solid state Nebo SVU AESA design. The L-band component antenna has a reduced aperture size compared to the semi-trailer hosted 59N6E radar. Available imagery of prototype hardware shows the VHF-band and L-band components, both of which were not previously available in self-propelled all terrain configurations, unlike the Gamma S1/S1E. The KU vehicle in the suite is the operator van. Each vehicle has an independent generator rated at 100 kiloWatts. All radar vehicles have an integrated hydraulic stow and deploy system for folding and unfolding the antenna, to support shoot-and-scoot operation, and all are equipped with dual mode GPS/Glonass navigation systems for this purpose. All radars are cited as solid state AESAs, with the capability to operate in an agile beam sector search/track regime, or in a conventional circular scan regime, with the antennas mechanically rotated. The idea of integrating three radars, each operating in a discrete band, is novel and clearly intended to provide a counter-VLO capability. ####################################################################################### A track fusion system in the KU vehicle will be required, providing a capability analogous to the US Navy CEC (Cooperative Engagement Capability)system. This technology was previously developed for the Salyut Poima E track fusion system and is now becoming mature. http://www.ausairpower.net/APA-Rus-Low-Band-Radars.html#JY-27 The Nebo-M system is clearly designed to hunt the F-35 Joint Strike Fighter. The VHF-Band component of the system provides sector search and track functions, with the X-Band and L-Band components providing a fine track capability. By good placement of the radars relative to the threat axis, the L-Band and X-Band components illuminate the incoming target from angles where the target RCS is suboptimal. Attempts to jam the Nebo-M will be problematic, since all of these radars have a passive angle track capability against jammers, as a result of which usage of a jammer permits passive triangulation of the target using three angle track outputs. The RLM-S and RLM-D have better elevation tracking accuracy than the RLM-M, and therefore the Nebo M should be capable of producing high quality tracks suitable for midcourse guidance of modern SAMs and full trajectory guidance of legacy SAMs For instance, let us consider the F-35 JSF in the 2 metre band favoured by Russian VHF radar designers. From a planform shaping perspective, it is immediately apparent that the nose, inlets, nozzle and junctions between fuselage, wing and stabs will present as Raleigh regime scattering centres, since the shaping features are smaller than a wavelength. Most of the straight edges are 1.5 to two wavelengths in size, putting them firmly in the resonance regime of scattering. Size simply precludes the possibility that this airframe can neatly reflect impinging 2 metre band radiation away in a well controlled fashion.

milstar: The seeker is reported to operate in ESM, J-band (10-12 GHz) and K-band (27-40 GHz) modes, using the last in the terminal phase to select specific ############################################################################################## targets.

milstar: Еженедельный дайджест Радиоэлектроника Пентагон продлил контракты на создание нового радара для ВМС Министерство обороны США продлило контракты на создание нового радара противоракетной обороны AMDR для ВМС, сообщает Defense News. 30 сентября были заключены новые соглашения с тремя американскими компаниями Northrop Grumman, Lockheed Martin и Raytheon, которые получили 120, 119 и 112,3 миллиона долларов соответственно. Работы над радиолокационной станцией продлятся до 2012 года. AMDR будет устанавливаться на боевые корабли различных типов. В частности, согласно планам ВМС США, начиная с 2016 года эсминцы класса Arleigh Burke "Серии III" получат такие радары. В настоящее время ведется разработка технических требований к таким кораблям, выпуск которых запланирован на 2016-2031 годы. Всего ВМС США намерены закупить 24 эсминца класса Arleigh Burke. Сейчас на эсминцы этого класса устанавливаются радары системы Aegis, которая в перспективе использоваться не будет. AMDR будет состоять из трех составляющих систем: двух основных радиолокационных станций S и X диапазонов и системы управления РЛС. Радар диапазона S будет обеспечивать объемный поиск и обнаружение баллистических ракет, а также связь и наведение противоракет. РЛС диапазона X будет отвечать за сопровождение целей, их подсветку и дополнительное наведение противоракет. В рамках новых контрактов компании будут вести разработку двух систем: радара диапазона S и системы управления. Работы по созданию РЛС диапазона X начнутся позже и будут распределены между компаниями после заключения дополнительных контрактов. 04.10.2010 Права на данный материал принадлежат Lenta.ru Материал был размещен правообладателем в открытом доступе.

The design goals of DBR are to: • Operate in harsh littoral environments, which often include potentially high-clutter areas, as well as land-based jamming • Provide automated ship self-defense capabilities against air and surface targets, including low-flying missiles • Provide robust multimission radar • Provide advanced electronic protection (EP) capabilities The REX consists of a digital and an analog portion. The digital portion of the REX provides system-level timing and control. The analog portion contains the exciter and the receiver. The exciter is a low-amplitude and phase noise system that uses direct frequency synthesis. The radar’s noise characteristics support the high clutter cancellation requirements required in the broad range of maritime operating environments that DBR will likely encounter. The direct frequency synthesis allows a wide range of pulse repetition frequencies, pulse widths, and modulation schemes to be created. The receiver has high dynamic range to support high clutter levels caused by close returns from range-ambiguous Doppler waveforms. The receiver has both narrowband and wideband channels, as well as multichannel capabilities to support monopulse processing and sidelobe blanking. The receiver generates digital data and sends the data to the signal processors. The Cobra Judy Replacement (CJR) Program includes the design, development, and acquisition of a functional replacement ship and mission equipment (ME) suite for the current Cobra Judy and USNS Observation Island. The CJR’s treaty verification mission will remain the same as the system it replaces, and it will continue to provide worldwide, high-quality, high-resolution, multiwavelength radar data. The systems aboard the replacement ship will include high-power, instrumentation- class, X-band and S-band phased-array radars and the necessary ancillary equipment to support the mission. A close-up of Cobra Judy S-band phased array and X-band dish antenna is shown in Figure 2. The X-band radar and its antenna dimensions are shown in Figure 3, with the array halves being test-fit for the X-band array shown in Figure 4. Both the X-band and S-band radars will employ a variety of waveforms and bandwidths to provide operational flexibility and high-quality data collection. The X-band radar will provide very high-resolution data on particular objects of interest, while the S-band radar will serve as the primary searchand- acquisition sensor and will be capable of tracking and collecting data on a large number of objects in a multitarget complex. The S‑band antenna dimensions are shown in Figure 5, with an overall size very similar to the X-band antenna. A common back end (CBE) will handle all controls and signal processing for both X- and Sband arrays. The CBE includes: • Displays • Processing Software and Equipment • Communication Suite • Weather Equipment cobra judy foto 14 metrow na 8.70 metra X band radar ########################################

Mod-anode modulation was provided by two vacuum switch tubes located 30 meters above the transmitter room in the RF head. Hardwired logic and timers signifi cantly complicated the diagnosis of transmitter faults and ease of resuming system operation after a fault.

milstar: AN/SPG-62 Fire Control Radar The Raytheon/RCA AN/SPG-62 is an I/J-Band fire control radar on Aeigis-class ships operates as a component of the MK-99 Fire Control System (FCS). FCS controls the continuous wave illuminating radar, providing a very high probability of kill. The Mk-99 Fire Control System also controls the target illumination for the terminal guidance of Ship Launched SM-2 Anti-Air Missiles. The AN/SPG-62 is a continuous wave, illumination radar for the Standard SM-2 missile as part of the Mark 99 fire-control system in the Aegis air defense missile system. The Aegis ships have three (DDG-51) or four (CG47) Mk 99 missile control directors that use the SPG-62 illumination channel to provide radar reflections for Standard missiles. Physical resemblance to the AN/SPG-52. The SPY-1 radar system detects and tracks targets and then points the SPG-62 toward the target, which in turn provides illumination for the terminal guidance of SM-2 missiles. In order to track a target a very narrow beam of RF energy is needed. The narrower the beam, the more accurately it is possible to tell whether there is one target or multiple targets (this is called radar resolution). This narrow beam radar is normally a second radar that works with a primary search or track radar. The AN/SPG-62 illuminating radar works as a second radar with the AN/SPY-1 series radar. Antenna Dimensions: 7 ft 5 in (2,286 mm) diameter Band: I-J (8-20 GHz) Peak Power: 10 kW (average) http://www.globalsecurity.org/military/systems/ship/systems/an-spg-62.htm http://en.citizendium.org/wiki/File:Antenna_suite_on_CG-60_Normandy_AEGIS_cruiser.jpg The AN/SPG-62 is a continuous wave, mechanically steered, terminal guidance illumination radar for the RIM-156 Standard SM-2 missile. These missiles use semi-active radar homing for their final guidance, so the Mark 99 fire control subsystem of AEGIS time-shares the illumination radars. Other functions of the Mark 99 system include loading, arming and launching the Standard missiles using the vertical launch system. Three AN/SPG-62 antennas are visible, at far left and second from rightPrimary search and midcourse guidance comes from the AN/SPY-1 phased-array radar, Only as the missile is making final approach to its target does there need to be AN/SPG-62 energy on the target, so the AEGIS battle management system can have more missiles flying against more targets than it has illuminators. Burke-class and Kongo-class destroyers have three and Ticonderoga-class cruisers have four AN/SPG-62's. Spanish F-100 frigates, versions of which are used by Australia, Norway and South Korea, have two. These radars, made by Raytheon, operate in the I/J bands with a peak power of approximately 10 kilowatts. Obviously, the specific operating frequencies change frequently and are classified, for reasons of protecting the missile guidance system from the target's electronic countermeasures (i.e., its self-protection electronic attack capabilty http://en.citizendium.org/wiki/SPG-62

Passive phase array with diametr 3.7 metr 3.1 -3.45 ghz AEGIS ships have a more effective radar at their disposal, however: the AN/SPY-1B/D/E passive phased array S-band radar can be seen as the hexagonal plates mounted on the ship’s superstructure. SPY-1 has a slightly shorter horizon than the SPS-49, and can be susceptible to land and wave clutter, but is used to search and track over large areas. It can search for and track over 200 targets, providing mid-course guidance that can bring air defense missiles closer to their targets. Some versions can even provide ballistic missile defense tracking, after appropriate modifications to their back-end electronics and radar software. Lockheed Martin’s SPY-4 Volume Search Radar (VSR) is an S-band active array antenna, rather than the SPY-1’s S-band passive phased array. The Navy was originally going to use the L-band/D-band for the DBR’s second radar, but Lockheed Martin had been doing research on an active array S-band Advanced Radar (SBAR) that could potentially replace SPY-1 radars on existing AEGIS ships. A demonstrator began operating in Moorestown, NJ in 2003. That same year, its performance convinced the Navy to switch to S-band, and to make Lockheed Martin the DBR subcontractor for the volume search radar (VSR) antenna. It also convinced Lockheed Martin to continue work on the project as a complete, integrated radar, now known as “S4R”. S-band offers superior performance in high-moisture clutter conditions like rain or fog, and is excellent for scanning and tracking within a very large ############################################################################################### volume. ###### While Lockheed Martin makes the VSR antenna, the dual-band approach means that Raytheon is responsible for the radars’ common back-end electronics and software. 3 ... The 3rd component is the AN/SPG-62 X-band radar “illuminators,” which designate targets for final intercept by air defense missiles; DDG-51 destroyers have 3, and CG-47 cruisers have 4. During saturation attacks, the AEGIS combat system must time-share the illuminators, engaging them only for final intercept and then switching to another target.
