The existing aerial surveillance system has PSR(Primary Surveillance Radar), SSR(Secondary Surveillance Radar). But continuous increase of the volume of air traffic has performance limit of radar-based aviation surveillance system. Recently, developed countries are adapted to using new surveillance system. In order to retain aviation safety, we introduce multilateration, ADS-B(Automatic Dependent Surveillance-Broadcast).
In this paper, we analyze Link budget of ADS-B signal for Multilateration. Multilateration divide into LAM(Local Area Multilateration) and WAM(Wide Area Multilateration) according to surveillance coverage. By knowing transmitter power and Surveillance coverage, it is possible to calculate received power. Then, received power is compared to Minimum Trigger Level(MTL) that is necessary minimum input power at receiver. Be more than Minimum Trigger Level(MTL), receiver can be obtained reliable information for Automatic Dependent Surveillance-Broadcast(ADS-B) report. By adding link margin at MTL, it is possible to de safety communication at receiver. These conclusion verify by computer simulation.
