DETERMINATION OF COUNTERMEASURES TO BISTATIC RADAR

A STUDY IS PROPOSED TO DETERMINE COUNTERMEASURE TO BISTATIC RADAR SYSTEMS. BISTATIC SYSTEMS OFFER POTENTIAL ADVANTAGES FOR SURVEILLANCE, ESPECIALLY AS AIRCRAFT AND MISSILES ARE DEVELOPED WITH REDUCED RADAR SIGNATURES. THESE ADVANTAGES ARE ENHANCED RADAR CROSS SECTION OVER A LIMITED RANGE OF BISTATIC ANGLES, REDUCTION OF PROPAGATION LOSSES, AND REDUCED VULNERABILITY TO JAMMING. COUNTERMEASURES WILL BE DETERMINED THAT WILL NEGATE THESE ADVANTAGES OR DEFEAT BISTATIC SYSTEMS. PASSIVE METHODS CONSIDERED WILL INCLUDE DENIAL OF ADVANTAGEOUS GEOMETRIES, RADAR ABSORPTION, BODY SHAPING, AND PHASING OF PRINCIPAL SCATTERERS. ACTIVE METHODS WILL INCLUDE JAMMING, REPEATERS (SPOOFING), AND CANCELLATION. EMPHASIS WILL BE PLACED ON HYBRID BISTATIC SYSTEMS (SPACEBORNE TRANSMITTERS, AIRBORNE RECEIVERS). COUNTER-COUNTERMEASURES WILL BE CONSIDERED. THE RESULTS WILL INCLUDE RECOMMENDED COUNTERMEASURES OR COMBINATIONS OF COUNTERMEASURES, AND DEFINITION OF NEEDED TESTS OR MEASUREMENTS TO DEMONSTRATE THE VALIDITY OF THE RECOMMENDATIONS.
