Abstract
The Canadian Department of National Defence has developed an airborne Synthetic Aperture Radar Motion Compensation System (SARMCS) for the AN/APS-506 Maritime Search Radar. To attain high quality airborne SAR imagery, the SARMCS must provide accurate information on spurious motion of the antenna phase centre during a SAR scene. This information is used to compensate the radar returns, thereby enhancing the SAR image quality. The SARMCS is effectively an integrated navigation system consisting of a ring laser gyro inertial navigation system (LTN-91), a Decca doppler radar, a baro-altimeter, and a motion compensation inertial measurement subsystem (MCIMS). The paper describes the hardware and software configurations of the SARMCS implemented on board a Convair 580 research aircraft. In addition, the flight testing approach and some of the simulation and flight test results are presented.
