This paper documents work performed at the McDonnell Douglas Astronautics Company in the field of optical signal processing as related to the processing of radar ambiguity functions. Included is a brief explanation of the two-dimensional range/doppler ambiguity function and a scheme for optically implementing it. Data is simulated digitally and optically. The optical process is documented at each point within the system. The final optical result is compared with the digital processor result, showing parallels in the fidelity of the ambiguity function.
