Abstract

Abstract: For residual clutter caused by system errors and motion errors in spaceborne SAR-GMTI with three channel when using displaced phase center antenna(DPCA) technology to suppress clutter, a novel method of detection and position for moving target was presented based on error compensation. Aiming at elimination of residual clutter, errors were analyzed in detail and corresponding compensation functions were derived. After compensation, DPCA and interferometric processing were applied to cultter suppression and moving target position.
