ELECTRO-OPTICAL SIGNAL PROCESSING TECHNIQUES FOR PHASED ARRAY ANTENNAS

Abstract

The research program for the development of electrooptical signal processing techniques applicable to phased array antenna systems in continued. A brief analysis of the planar array processor formed by combining the 'spatially multiplexed' and 'time-delay multiplexed' linear array processor techniques is presented. A description of the experimental system and the results obtained when processing signals simulating the output from a uniformly weighted planar array of 576 elements is included. The output response is very nearly ideal for signals on and off the boresight axis. The experimental results obtained with a spatial filter system at the laser output beam, and the frequency response of the multiple transducer are included. The theory and techniques developed for aperture weighting in the time-delay multiplex signal simulator are discussed.
