ELECTRONIC RECEIVER SYSTEMS

A NEW CLASS OF LINEAR FILTERS ARE EMERGING WHICH UTILIZE ACOUSTO-OPTIC TECHNOLOGY TO PROVIDE PROGRAMMABLE OR ADAPTIVE, HIGH-Q, LINEAR FILTERING OF BROADBAND (20-2000 MHZ) ELECTRONIC SIGNALS. THESE HIGH DYNAMIC RANGE FILTERS CAN BE PROGRAMMED OR ADAPTED DIRECTLY IN THE FREQUENCY DOMAIN. RECENT (1983) EXPERIMENTS BY PROBE SYSTEMS HAVE SHOWN THAT THIS FILTER TECHNOLOGY CAN RAPIDLY AND SELF-ADAPTIVELY REJECT MULTIPLE NARROWBAND JAMMER SIGNALS FROM BROADBAND SIGNALS WITH EXTREMELY NARROW DEEP, LINEAR-PHASE NOTCH FILTERS. APPLICATIONS INCLUDE SIGNAL INTERFERENCE OR JAMMER REJECTIOIN FOR BROADBAND SURVEILLANCE, WARNING, AND DIRECTION FINDING REFEIVERS AS WELL AS SPREAD SPECTRUM COMMUNICATION AND RADAR SYSTEMS DESIGNED TO OPERATE IN HIGH INTERFERENCE ENVIRONMENTS. THE PROPOSED EFFORT WOULD INVOLVE ANALYZING THE POTENTIAL ERFORMANCE AND COST IMPROVEMENTS WHICH THIS NEW LINEAR ACOUSTO-OPTIC FILTER TECHNOLOGY COULD PROVDIE WHEN APPLIED TO BROADBAND ELECTRONIC SURVEILLANCE AND WARNING RECEIVERS AS WELL AS SPREAD SPECTRUM COMMUNICATION AND RADAR SYSTEMS. THESE PERFORMANCE AND COST IMPROVEMENTS WOULD BE COMPARED TO ALTERNATE CURRENT AND FUTURE TECHNOLOGIES. ALSO, POSSIBLE TECHNOLOGY GAP AREAS FOR FABRICATING THE FILTERS WOULD BE IDENTIFIELD.
