Abstract

The detection and recognition of helicopter and propeller-driven fixed-wing aircraft in passive bistatic radar utilizing signals of DVB-T2 standard as an illuminator of opportunity are discussed in this paper. The recognition algorithm is based on analysis of the modulation components of the echo signal caused by aircraft rotational constituents. The results of experimental verification with real echo signals from Mi-8 helicopter and Cessna 172 fixed-wing aircraft recorded by two individual passive bistatic radars are presented.
