Algorithms for Synthetic Aperture Radar Imagery XXIII.
Advanced spread spectrum linear frequency modulated (LFM) waveforms are being developed for advanced capability synthetic aperture radar (SAR) and ground moving target indication (GMTI) applications. We have demonstrated by analysis and simulation th

40-years of digital SAR and Slow GMTI technology is traced from the first system to demonstrate real-time digitally correlated SAR from an intentionally maneuvering platform [1] to the current lite-weight dual-channel radar (DCR) providing simultaneo

In this research, we have developed an algorithm to reduce the residual artifacts of the background clutter (that is, stationary targets) that appear in the MTI imagery that are generated by Global Signal Subspace Difference (GSSD) of the monostatic

This paper is concerned with imaging and moving target detection using a Synthetic Aperture Radar (SAR) platform that is known as Gotcha. The SAR platform can interrogate a scene using an imperfect circular trajectory; we refer to this as nonlinear S
