Detection Rate with SSR Mode-S Squitter Measured by New Aircraft Surveillance System Adopting Tri-Lateration Method

Naoki Fujii

Abstract:	Some aircraft have Secondary Surveillance Radar (SSR) mode-S transponder with unortholized aircraft address. The unortholized aircraft address interferes to Aircraft Collision Avoidance System (ACAS) and SSR mode-S communication system. Therefore Aircraft Address Monitoring System (AAMS) has been developed by Electronic Navigation Research Institute (ENRI) in Japan. This paper introduces the outline of a new type of aircraft surveillance system called AAMS adopting tri-latemtion method and its evaluation results focusing on the target detection rate with SSR mode-S squitter. The result of flight check shows that the detection rate for AAMS with SSR mode-S squitter within its perspectival coverage is more than 25%, and the detection rate for Automatic Dependance Surveillance Broadcast mode (ADS-B) system is more than 60% within its perspectival coverage.
