The goals of this effort were to demonstrate the applicability of adaptive differential synthetic aperture radar ADSAR techniques to radar data collected from conformal arrays with three or more channels. The ADSAR technique first generates complex images at each channel, using SAR or SAR-like techniques so that the clutter is as nearly identical as possible in each channel. By taking the known collection geometry into account, some aspects of the clutter statistics are made nearly stationary over range, Doppler, and spatial channel. This reduces the number of degrees of freedom DOF required to cancel the clutter, using traditional Space-Time Adaptive Processing STAP techniques. The resulting ADSAR-STAP techniques were to be studied in terms of their performance in the detection and localization of ground moving target indication GMTI. This effort was terminated at the convenience of the government for lack of technical progress.
