Hybrid electro-optic processor
Abstract
This report describes the design of a hybrid electro-optic processor to perform adaptive interference cancellation in radar systems. The processor is designed to process wideband interference signals as well as multipath copies of these signals. The optical components in the processor include acousto-optic cells used as delay lines, a charge coupled device linear detector array, and a transmissive liquid crystal display spatial light modulator. The spatial light modulator is driven by an electronic microprocessor. A new way of achieving improved dynamic range for such a spatial light modulator is reported. Included in this report is a discussion of the design, partial fabrication in the laboratory, and partial testing of the hybrid electro-optic processor. A follow on effort is planned to complete the construction and testing of the processor. The work described in this report is the combined effort of RADC in-house project 4600P103 and Contract F30602-88-D-0027.
