Tactical Persistent Surveillance Radar with Applications [EPUB ebook] 

Support

Tactical Persistent Surveillance Radar with Applications introduces technologists to the essential elements of persistent surveillance of tactical targets from both a hardware and software point of view, using simple Mathcad, Excel and Basic examples with real data. It is based on the type of surveillance done by drones like Scan Eagle, Predator, Reaper, Global Hawk, and manned aircraft like U-2, ASTOR, and JSTARS as well as spacecraft. The general topic is cellphone and datalink intercept, ground moving target radar, synthetic aperture radar, navigation, tracking, electronic scanning and cueing electro-optical sensors for activity based surveillance.Examples are taken from a wide range of technologies and techniques including passive detection, radar detection, antenna monopulse, active electronic scanned antennas (AESA), moving target tracking (MTT), motion compensation, tactical target spectral characteristics, moving target detection (MTI), space time adaptive processing (STAP), synthetic aperture radar (SAR) imaging, change detection (CCD), and synthetic monopulse.Over 120 example applications programs are included in the appendices and as downloads as well as over 100 SAR and GMTI raw IQ data files. These allow the curious to experiment with their own parameters and notions to achieve a greater understanding of the underlying behaviors.Based on the author’s 55-year experience in engineering design, leadership, teaching and consulting, this book is an essential text for researchers, advanced students and technologists working in radar and related fields in computing and aerospace system design.
