Abstract
ADVANCED REENTRY VEHICLES ARE BEING PROPOSED THAT USE ON-BOARD ELECTROMAGNETIC SYSTEMS FOR ACCURACY IMPROVEMENT (TERMINAL HOMING AND TERRAIN SENSORS) AND ECM APPLICATION. THE PERFORMANCE OF THESE SYSTEMS IS DEGRADED BY THE EFFECTS OF NON-UNIFORM ANTENNA WINDOW ABLATION AND THE BOUNDARY LAYER AND SHOCK LAYER PLASMA WHICH FORM DURING ATMOSPHERIC REENTRY. THE COMPLEXITY OF THIS PROBLEM IS BEYOND THE SCOPE OF PRESENT DAY ANALYTICAL METHODS. GROUND TESTS ARE REQUIRED TO COMPLEMENT THE ANALYSES. APPROPRIATE SIMULATION MUST BE ACHIEVED FOR THE TESTS TO BE USEFUL. WE PROPOSE TO DESIGN INNOVATIVE GROUND TESTS USING EXISTING FACILITIES TO PROVIDE THE DATA FOR THE ASSESSMENT OF REENTRY VEHICLE ELECTROMAGNETIC SIGNAL PROPAGATION.
