A Radar System Application Of Optical Signal Processing

This paper documents internally funded optical signal processing (OSP) work performed at the McDonnell Douglas Astronautics Company. The concepts deal with the current digital radar signal processor configuration and an OSP system that simulates the algorithm sequence of its digital counterpart. A 16-pulse Frank polyphase (FPP) waveform of Order 7 is processed both optically and digitally. The results from both processing systems are compared and it is determined that the accuracy and fidelity of the OSP approach are still not equal to those of the digital processor. However, the use of OSP is justified because parallel processing of multiple wavefornis using OSP techniques can solve the spline-rejection problem.
