Motion Compensation SAR-Processing Facility at DLR.

For the experimental SAR of DLR (E-SAR) a SAR-processor was developed to perform range and motion compensated azimuth compression. The E-SAR of DLR is described by (Horn, 1989, 1990). The motion compensation processor consists of a range compression module,a motion extraction module, a motion compensation module and an azimuth compression module. The motion extraction module is able to extract the displacement in line of sight (LOS) direction, the aircraft's drift angle and the forward velocity. In this paper, the motion compensation processor will be described, the off-line/on-line implementation possibilities will be given, followed by practical results.
