APPLICATION OF DIGITAL RF MEMORIES TO MULTISTATIC RADAR TECHNOLOGY

SEVERAL ISSUES IMPACTING THE SUCCESSFUL IMPLEMENTATION OF MULTISTATIC RADAR SYSTEMS CONTINUE TO REQUIRE RESEARCH. ONE SUCH ISSUE IS ACHIEVING COHERENCY BETWEEN TRANSMITTER AND RECEIVER. THIS PROPOSAL ADDRESSES THE USE OF A DIGITAL RF MEMORY (DRFM) IN ORDER TO DO SO. THE DRFM OFFERS THE ADDITIONAL POTENTIAL OF PROVIDING A TARGET RECOGNITION AND CLUTTER REJECTION CAPABILITY IN ADDITION TO ACHIEVING COHERENCY. A 2 PHASE PROGRAM IS PROPOSED; IN PHASE I SIGNAL PROCESSING REQUIREMENTS COMMON TO DIFFERENT TYPES OF MULTI-OR BI-STATIC RADAR OPERATIVES WILL BE IDENTIFIED IN ORDER TO DERIVE CANDIDATE IMPLEMENTATIONS. SELECTED REQUIREMENTS WILL BE MODELED TO PREDICT OVERALL RECEIVER PERFORMANCE AND OPTIMUM IMPLEMENTATION. THIS WOULD PROVIDE THE GROUNDWORK FOR A PHASE II EFFORT TO DESIGN, FABRICATE, AND TEST A BRASSBOARD RECEIVER SYSTEM TO DEMONSTRATE THE CONCEPT. THE PROPOSED EFFORT WILL BE PERFORMED BY PERSONNEL DOMINANT IN THE DRFM FIELD.
