The technology and system design of radars to survey a battlefield has a relatively short history, starting in about 1968. The early technology was developed to provide detection of both fixed and moving targets, along with discovery and tracking of military positions. And the system operational architecture required either long standoff range or flying on a small, remotely piloted air vehicle. These...
Multimode airborne radars have been in development for 40 years, providing detection and tracking of both fixed and moving targets. Electronic scanned arrays provide the ability to rapidly switch modes, and survey widely separated areas. However, the demands on high bandwidth and long dwells to separate fixed targets from background clutter counter the high area coverage rate for moving targets. This...
In this paper we discuss the frequency-jump burst (FJB) waveform as a candidate for performing joint synthetic aperture radar (SAR) imaging and ground moving target indication (GMTI). We introduce the signal model for simulating SAR data and the method for image formation. The ambiguity function (AF) is used as an analysis tool for determining whether the waveform under investigation has the desired...
Surveillance RADARs normally share time for detecting fixed and moving targets. With modern digital waveform synthesis and high performance computing, it is feasible to collect signals that use space, time and frequency encoding to simultaneously operate in GMTI and SAR modes. This paper summarizes a new waveform and adaptive RADAR architecture with the potential for simultaneous SAR and GMTI operation,...
