Anti-jamming techniques for multichannel SAR imaging [PDF]
IEE Proceedings - Radar, Sonar and Navigation, 2006 An airborne broadband jammer present in the mainbeam of a synthetic aperture radar (SAR) can potentially destroy a large region of the SAR 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.
