Abstract:

The objective of this contract was to design, fabricate, and test an optical processor to perform an ambiguity function to detect relative time delay and frequency shift between a pair of passive sonar receivers. The optical architecture used in this program is the unique linear phase shifter LIPS architecture which was developed at Honeywell. The support electronics for the optical processor were designed around a PDP-1123 minicomputer. The PDP-1123 controls the functions of the optical processor, stores input and output data, and provides IO to an outside Host computer. Real sonar data on synthetic calibration data were processed to demonstrate the functionality of the system. Overall, the objectives of this program were completed. The result of this program was the development of an optical processing system capable of supporting different optical architectures or processing scenarios. Using a minicomputer controller gives the system the required flexibility to handle different tasks. The LIPS optical architecture used for this program is capable of running at 500 framesseconds if it were not IO limited at the detector output. This rate corresponds to approximately a 10 giga-multiplyadds per second processing rate. The electronic IO limited the processing rate to approximately 5 framessecond.
