Abstract
Optical signal processing architectures have been designed which offer potential solutions to Air Defense Initiative (ADI) radar signal processing requirements for low radar cross-section target detection and noncooperative target recognition (NCTR). A rack-mounted engineering development model of a wide-bandwidth acousto-optic correlator has been developed to provide high range resolution for target feature extraction and discrimination. A wideband acousto-optic range-Doppler processor brassboard has also been designed to provide simultaneous high range resolution and Doppler filtering. Design and fabrication of a test radar subsystem is in progress, and will be utilized as an ADI clutter suppression test-bed for integration and testing of the high resolution acousto-optic correlator engineering development model and the acousto-optic range-Doppler processor brassboard. In this paper, the designs and status of the optical processors and test-bed are described.
