Modern digital simulation of airborne sensor performance and vulnerability

The capabilities and structure of three airborne radar system simulations are presented. The air-to-air electronic countermeasures model was developed to evaluate the performance of pulsed Doppler radar sensors in an electronic warfare environment. The air-to-ground radar assessment model simulates several ground mapping modes of a modern pulsed Doppler radar system and their susceptibility to active and passive jamming. The terrain countermeasures seeker model was developed as a tool to analyze the effect of terrain countermeasures on sensor performance. Each simulation is reviewed with emphasis on its role in radar sensor vulnerability assessment. Representative output from each simulation is shown
