A multi-channel acousto-optic correlator is proposed as programmable radar signal detector for threat warning. The system is expected to detect pn sequence waveforms, fm, fm on pulses, and conventional pulses. High sensitivity is possible with special treatment of synchronized noises in the correlator. For conventional pulses, the system reduces to a channelized receiver. The Phase I program will analyze the performance and design issues with the multi-channel correlator. A breadboard design and program plan will be developed for the Phase II program.
