Holographic Imaging with Object Synthesized Apertures

A method for imaging remote moving objects with a giant thinned holographic array by monitoring the range and range-rate (Doppler) histories of a coherently illuminated object at the various elements of the array is discussed. Electrooptic processing and image retrieval from the raw data collected are described together with a technique that compensates for image distortion arising from irrotational object maneuvers. Results of confirming experiments are also given together with remarks on practical implementation.
