RANGE/AZIMUTH ANGLE SHIP IMAGING FOR ORDNANCE CONTROL ABSTRACT 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 inter- ferometric 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 imbedded in a single designated resolution cell of the ship's displayed image essential to carrying out precision stand- off command weapon guidance to that selected ship target cell, can be accomplished.
