Signal reconstruction as an effective means of detecting targets in a DAB-based PBR

Abstract

This paper aims to validate the method of target detection by correlating a surveillance (target) signal with a reconstructed reference signal in DAB-based Passive Bistatic Radar (PBR). Whereas most conventional PBRs condition the surveillance signal by suppressing Direct Signal Interference (DSI) and then correlate this with a similarly measured reference signal to reveal targets, the approach adopted at FHR is to correlate the surveillance signal with a perfectly reconstructed, error-free, copy to the transmitted signal.
