Abstract : The Air Route Surveillance Radar at Suitland, Maryland was selected as the location to predict the performance of the three types of transponders considered in the analysis (Military, Air Carrier, and General Aviation). The interrogator environment consisted of IFF/ATCRBS interrogators deployed within an 850 nautical-mile radius of Suitland and the aircraft transponder deployment consisted of aircraft at various azimuths, altitudes, and ranges within a 200 statute-mile radius of Suitland. For the deployed aircraft, different percentages of aircraft were designated as having out-of-tolerance transponders. The AIMS Performance Prediction Model was used to predict the performance of the Suitland interrogator for both in-tolerance and out-of-tolerance transponder characteristics for the three types of transponders analyzed.
