Download or read book Optical Beamforming Networks for Radars Electronic Warfare Applications written by Jean Chazelas and published by . This book was released on 2003 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Future microwave systems will be generally based on active electronic antennas. This evolution is determined by requirements of improved performances of these equipments in terms of reliability, jamming resistance, flexibility for the beamformning in the transmit and in the receive mode. Such antennas will be use in a large number of applications such as radar, communication and electronic warfare. In order to satisfy this multiftuictional aspects, it will be necessary to distribute these antennas on ground based areas as well as the aircraft surface. Multistatic systems will impose multiple remoting of antennas with respect to their processing units. In all cases, it appears a need for low loss link able to remote the control of the antennas as well as distribution and processing of very wideband microwave signals (typ. 1-20 GHz). Maturity and performances (in terms of spectral purity or phase noise, dynamic range linearity) of optoelectronic components permit to envisage the optical transmission and the optical processing of these signals. Today, the optical transmission of microwave signals offers in conjunction with their low loss propagation over very wide frequency bandwidth, a high immunity to electromagnetic perturbations, which opens new avenues for the insertion of new concepts and photonic architectures in microwave systems. Photonics and microwave technologies offers new opportunities for controlling many thousand - array elements together with handling the wide bandwidth of shared aperture antennas. Photonics technologies will provide an interconnect solution for future airborne phased array radar antennas, which have conformality, bandwidth, EMI immunity, size, and weight requirements increasingly difficult, if not impossible, to meet using oonventionnal electrical interconnect methods.

Book excerpt: Microwave photonics is an emerging interdisciplinary area that investigates the deep interactions between microwaves and light waves for efficient generation, distribution, processing, control, and sensing of microwave, millimeter-wave, and terahertz signals. This book outlines the potential for microwave photonics in radar and electronic warfare systems, covering basic concepts and functions, comparing performance with conventional systems, describing its impact on digital signal processing, and exploring integration issues. The main hardware functionalities provided by photonics in radar and EW systems are described: RF transport in optical fiber, photonics-based RF signal generation/up-conversion and analog-to-digital conversion/down-conversion, optical beamforming and optical RF filtering. The book describes the new radar and EW system architectures enabled by photonics, highlighting its potential in reducing the size, weight, power consumption and cost of the whole radar or EW systems. The book also reports new applications made possible by on-chip system implementations. Chapters are written by global experts in radar, radar networks, electronic warfare systems and microwave photonics, who have been or are currently collaborating on these new applications of photonics at a system level, providing detailed and clear interdisciplinary information at research and industrial level for both the radar/EW and photonics communities.

This book was released on 2016-10-19 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers a thorough understanding of the applicability of new-generation silicon-germanium (SiGe) electronic subsystems for electronic warfare and defensive countermeasures in military contexts. It explains in detail the theoretical and technical background, and addresses all aspects of the integration of SiGe as an enabling technology for maritime, land, and airborne / spaceborne electronic warfare, including research, design, development, and implementation. The coverage is supported by mathematical derivations, informative illustrations, practical examples, and case studies. While SiGe technology provides speed, performance, and price advantages in many markets, to date only limited information has been available on its use in electronic warfare systems, especially in developing nations. Addressing that need, this book offers essential engineering guidelines that especially focus on the speed and reliability of current-generation SiGe circuits and highlight emerging innovations that help to ensure the sustainable long-term integration of SiGe into electronic warfare systems.

Download or read book Beamforming Sensor Signal Processing For Defence Applications written by Athanassios Manikas and published by World Scientific. This book was released on 2015-03-19 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beamforming: Sensor Signal Processing for Defence Applications presents a range of important research contributions concerned with sensor array signal processing and, in particular, with the superresolution beamformers fundamental to many civilian and defence applications. Both space and space-time (STAP) beamforming algorithms and their application to radar systems are considered with emphasis given to 'look-down' airborne radars, synthetic aperture radar (SAR), arrayed MIMO radar and a number of common wake-wave detection algorithms for two-dimensional SAR imagery. Furthermore, ocean towed arrays, which find applications in a variety of areas such as defence, oil and gas exploration, and geological and marine life studies, are also considered paying particular attention to receiver positional uncertainties resulting from the array's flexible structure. Array geometrical and electrical uncertainties, design of auto-calibration algorithms, beamforming 'pointing' error uncertainties and robustification issues are also presented.This book is self-contained and unified in its presentation, and comprehensively covers some of the classic and fundamental models of beamforming for sensor signal processing. It is suitable as an advanced textbook for graduate students and researchers in the area of signal processing, as well as a reference book for engineers in the defence industry.
