dc.description.abstractForming a Synthetic Aperture Radar (SAR) image while suppressing a 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 will add a non-stationary interference component to the image. The goal of interference suppression for SAR is to successfully suppress these interferences while not significantly effecting the image quality by blurring, reducing the resolution or raising the side-lobe level. Using multiple antennas on a SAR provides spatial degrees of freedom and allows for adaptive beamforming to suppress the jammer signals. This paper presents two constrained spatial techniques which reduce the interference level without significantly effecting the image quality.
