Range/azimuth angle ship imaging for ordnance control

Abstract From the Canadian patent

Distortions inherent in the formation of a range/ doppler image by an airborne Synthetic Aperture Radar (SAR) of a ship under the influence of roll, pitch and yaw motions character-, istic of sea state conditions are removed by the formation of, a scaled range/azimuth angle image generated with the use of an interferometer antenna in conjunction with the SAR. A least squares linear regression solution to doppler processed interferometric azimuth angle data derived from ship radar reflections permits the determination of aircraft to ship relative rotational motion essential to the development of such an improved high resolution radar image, so that continuous automatic tracking of a cursor …
