New algorithm for signal detection in passive FSR

Abstract

This paper concerns with the passive forward scatter radar (FSR). An algorithm to extract the Doppler signature of a target is presented for the first time. It allows removal of the background modulation of the transmitted signal, so that the signature can be extracted within a narrow band. Receiver architecture, corresponding to the proposed algorithm experimental set-up and experimental results are shown, where a DVB-T signal has been used to test the passive FSR algorithm. The performance of the proposed algorithm is analyzed at this initial stage of the research.
