Abstract

Forming a synthetic aperture radar (SAR) image while suppressing an airborne broadband jammer can potentially destroy large regions of the image. In addition to this, multipath reflections from the ground known as hot clutter or terrain scattered interference (TSI) will add a nonstationary interference component to the image. A number of constrained fast-time space time adaptive processing (STAP) techniques are presented which exploit adaptive beamforming to suppress the interference with minimal distortion to the final image.
