ANTI-SIMULATION TECHNIQUES APPLICABLE TO BALLISTIC AND MANEUVERING REENTRY VEHICLES AND ASSOCIATED PENETRATION AIDS STUDY

THE DESIGNATION OF RVS AMONG A PAYLOAD OF LETHAL RVS, DECOYS, AND CHAFF REQUIRES REFERENCE FUNCTIONS DERIVED FROM UNIQUE FEATURES OF THE RVS AND, PERHAPS DECOYS. ANTI-SIMULATION SMEARS, OR DEGRADES, THE REFERENCE FUNCTIONS OF BOTH THE RVS AND DECOYS USING MODIFICATIONS TO THE SURFACE AND SHAPE SUCH AS PAINTS AND FAIRINGS. THE OBSERVER WOULD HAVE A FAR MORE DIFFICULT TIME DESIGNATNG THE RV WHICH IS SMEARED TO MORE CLOSELY RESEMBLE THE PENETRATION AIDS. THE PHASE I PROGRAM DESCRIBED IN THIS SBIR WILL DEFINE THE TARGET FEATURES THAT CAN BE MEASURED BY THE ANTICIPATED DISCRIMINATION SENSORS. THE ANTISIMULATION TECHNIQUES THAT COULD BE USED TO ALTER THE RV AS WELL AS THE PENETRATION AID SIGNATURES WILL BE INVESTIGATED IN SUFFICIENT DETAIL TO DEMONSTRATE THE FEASIBILITY OF THIS APPROACH TO INCREASE THE REENTRY SYSTEM EFFECTIVENESS. A PHASE II DEMONSTRATION PROGRAM INCLUDING SUBSCALE AND FULL SCALE TARGET MEASUREMENTS IN A RADAR ANECHOIC CHAMBER OR AN OPTICAL SPACE CHAMBER WILL BE PROPOSED AND THE COSTS DEFINED IN SUFFICIENT DETAIL TO PROVIDE A BASIS FOR A PHASE II PROGRAM.
