Airborne Transfer Alignment and SAR Motion Compensation

James L. Farrell

Abstract:	A synthetic aperture radar employing an electronically steerable array antenna is simulated for the case of an existant master inertial measuring unit (IMU) in a remote location. To obtain reliable motion compensation data a strapdown IMU is mounted within about a. foot of the antenna. Ramifications include (1) the approach to transfer alignment, (2) nav update for the master IMU, and (3) effects of motion-sensitive strapdown inertial instrument degradations on synthetic aperture radar (SAR) mode performance. These ramifications are addressed herein; although results are presented for simulation under simplified conditions only, the path has been prepared for full operational validation as discussed herein.
