milstar: HIGH PERFORMANCE PHOTONIC ADC FOR SPACE APPLICATIONS Other alternative to be able to digitize the bandpass signal, is the use of downconversion which use a mixer and a local oscillator to beat this last signal with the incoming signal. After a filtering, the original signal is “converted” from RF (K-band, Ka-band …) to IF (Intermediate Frequency) where the E-ADC is able to work. Conventional analogue downconversion techniques exhibit also some limitations like the LO leakage, the image rejection or require the use of different downconversion and filtering stages (super-heterodyne configuration). If the application requires multiple branches, there will be limitations in size, mass (limited by mechanical isolations for avoiding EMI and leakage effects) and consumption. Table 1 depicts one example for 200 channel RF downconverter (information available in the Thales Alenia Space web page concerning standard single-channel downconverters): Table 1: Mass/Consumption estimation for 200 channel downconversion http://congrex.nl/icso/Papers/Session%206a/vernich.pdf In Fig. 2, the scheme of implementation of the future telecom payloads with 100-200 ADCs with the traditional solution (frequency converters) and with Electro-photonic ADCs is depicted.

milstar: Applying a High Performance Tiled Rad-Hard Digital Signal Processor to Spaceborne Applications BAE http://www.ann.ece.ufl.edu/courses/eel6686_15spr/papers/RADSPEED.pdf On-board processing may be performed in a variety of ways including 1) specialized radiation hardened application specific integrated circuits (ASIC) with their highest performance/watt but limited functional flexibility, 2) reprogrammable field programmable gate arrays (FPGA) with higher power requirements and additional challenges in radiation mitigation and configuration storage; 3) multi-core general purpose processors (GPP) with floating point units supported by COTS infrastructure but with lower overall performance and 4) multi-core digital signal processors (DSP) optimized for signal processing applications that provide programmability and high performance at a reasonable power. The RADSPEEDTM DSP - a radiation hardened version of the ClearSpeedTM CSX700 digital signal processor – is being developed by BAE Systems to provide a high performance per watt digital signal processor for these emerging spacecraft applications. The CSX700 is a best in class device in the commercial world and is used in a variety of graphics, financial, server and other signal processing applications supported by a full set of development tools. In hardening the RADSPEED DSP, over 70% of the performance of the commercial device was retained (70 GFLOPS peak performance) with a modest decrease in processing speed (8%) and the number of processing element cores (160 from 200). The RADSPEED DSP opens up a programmable world for specialized payload applications. This includes 1) various types of RF processing, 2) radar processing with the high throughput required for both Space-Time Adaptive Processing (STAP) and Synthetic Aperture Radar (SAR) algorithms, 3) hyperspectral imaging with the need for simultaneous processing of images across a number of frequency bands, fusing data for analysis, spectral analysis for the simultaneous assessment of data across a number of frequency bands and 4) image processing including edge and object detections and the efficient distribution of a high resolution image across a series of parallel processing elements. . RADSPEED DSP DEVELOPMENT The RADSPEED DSP is a variant of the ClearSpeedTM CSX700 [5] DSP. BAE Systems and ClearSpeed Technology modified the device for the space environment and for multi-device intercommunication. While the commercial ClearSpeed CSX700 includes a PCI Express interface and a single proprietary ClearConnect bridge (CCBR) interface, the RADSPEED DSP variant replaces the PCI Express port with a second CCBR. The inclusion of two CCBR buses allows “daisy-chaining” of the DSPs for increased processing performance. BAE Systems performed radiation hardening of the device through circuit and physical design modifications combined with the process hardening features available in BAE Systems’ RH90 90nm CMOS technology. The modifications required to achieve radiation hardening resulted in the decision to decrease the number of processing elements from 192 to 152 active processing cores, and the speed changed from 250 MHz to 233 MHz. These changes reduced the peak processing performance from 96 GFLOPS to 70 GFLOPs while keeping the power dissipation to 15W. The high performance bandwidth of the individual buses is maintained at the ~4GB/s. Figure 2 shows the completed device layout.

milstar: CRANE, Ind. – U.S. military researchers are boosting the defense industry's ability to integrate radiation-hardened microelectronics components for space applications, as well as those expected to operate through nuclear events like atomic explosions. Officials of the U.S. Naval Surface Warfare Center in Crane, Ind., announced a $10.3 million order Tuesday to Honeywell International Inc. in Minneapolis to help sustain the nation's strategic radiation-hardened microelectronics facility and production capability. The Honeywell Aerospace segment operates two advanced radiation-hardened microelectronics manufacturing facilities -- one in Plymouth, Minn., and the other in Clearwater, Fla. These are among the few remaining U.S. facilities for weapons-grade rad-hard integrated circuit manufacturing able to withstand radiation doses that exceed 1 megarad. Related: Space: the next frontier of rad-hard This order asks Honeywell to sustain the company's strategic radiation-hardened microelectronics capability through researching extensions of existing products and technology, radiation testing and analysis, and sustaining existing application specific integrated circuit (ASIC) product support and multi-project wafer test and modeling capability. The services are necessary to maintain a domestic trusted source for strategic radiation-hardened microelectronics to meet the U.S. Department of Defense (DOD) certification to Congress, as stipulated by the fiscal 2018 National Defense Authorization Act Section 1670, DOD officials say. Radiation-hardened microelectronics components are necessary for manned and unmanned spacecraft operating on long-duration orbital missions in high-radiation space environments like geosynchronous orbits. Related: Navy looks to L3Harris Applied Technologies for radiation-hardened trusted microelectronics testing equipment Rad-hard components also are necessary for mission-critical military applications like ships, aircraft, and land vehicles that would be expected to operate through the effects of nuclear explosions. Although there are several microelectronics designers able to produce components appropriate for some spacecraft, few companies remain that are able to produce components able to withstand long-duration exposure to intense radiation, or exposure to weapons-grade radiation. On this order Honeywell will do the work in Plymouth, Minn., and should be finished by March 2022.

В ее состав включались специальные предохранительные устройства, разрабатывалась архитектура электроники максимально устойчивая к ЭМИ. Конечно, если попасть в эпицентр применения электромагнитной бомбы большой мощности, то защита будет пробита, но на определенном расстоянии от эпицентра, вероятность поражения будет существенно ниже. Электромагнитные волны распространяются во все стороны (как волны на воде) поэтому их сила убывает пропорционально квадрату расстояния.

milstar: 3.1. Генераторы со сжатием потока при помощи взрывчатки Генераторы со сжатием потока при помощи взрывчатки (FC-генераторы) являются наиболее зрелой технологией, применительно к разработке бомб. FC-генераторы были впервые продемонстрированы Кларенсом Фоулером в Лос Аламосе (Clarence Fowler at Los Alamos National Laboratories, LANL) в конце 50-х годов. С тех пор был создан и испытан широкий набор конструкций FC-генераторов, как в США, так и в СССР, а позднее - в СНГ. FC-генератор - это устройство в относительно компактной упаковке, способное произвести электрическую энергию порядка десятков МДж за сотни микросекунд. С пиковой мощностью от единиц до десятков ТВт, FC-генераторы могут быть использованы прямо, или в качестве источника коротких импульсов для микроволновых генераторов. Для сравнения, ток, производимый большими FC-генераторами в 10-1000 раз больше, чем ток, производимым типичным ударом молнии [WHITE78]. https://web.archive.org/web/20111009091118/http://daily.sec.ru/publication.cfm?rid=45&pid=6276
