Abstract :
Digital Radio Mondiale (DRM)-based HF passive bistatic radar has massive potential for surveillance purposes. Progress about DRM based passive bistatic radar is described. Several key problems need to be overcome for the base-band signal processing, including the vice-peaks suppression of DRM signal ambiguity function, the rejection of direct-path and multipath clutter in the surveillance channel and the extraction of the reference signal in the reference channel. Relative solutions of these problems will be presented. In addition, some results based on simulation data are shown in this paper.
