Experimental Result of Fixed Structure Suppression for ISDB-T Passive Positioning

Abstract

Multi-Static Primary Surveillance Radar (MSPSR) is expected to be used for conventional primary surveillance radar alternative which uses scattered waves caused by aircraft. MSPSR that uses not only present radar signal but also other communication signals, is classified into passive radar. Among them, digital terrestrial television broadcasting (DTTB) is the most expected radio waves to cover larger area because the transmitted signals are always present and the transmitted powers are relatively large. We investigate a new surveillance system using ISDB-T which was adapted to Japanese DTTB. In this paper, we report experimental results of aircraft positioning in order to suppress reflected waves from fixed structures.
