Acousto-optic null steering processor (AONSP) hardware performance summary update

The development of an acousto-optic null steering processor for radar ECCM applicaiton is reviewed. The general problem to be solved by this special purpose signal processor is discussed and the advantages of the acousto-optic approach are given. Processor architecture, AO/EO component selection, and experimental discoveries are described. Measurements of the laboratory breadboard model's performance for a variety of multipath and non-multipath signals are also covered. Limitations of the current breadboard model and future directions are discussed.
