Passive Bistatic Radar
We can conclude that passive bistatic radar has come a long way since the first experiments in the early 1980s - and certainly since the first radar experiments using broadcast signals more than 50 years before that. Potentially, it offers covert operation with simple and low-cost equipment without the need for a transmitting license, and the ability to use parts of the elecromagnetic spectrum not normally available for radar use. The wide variety of broadcast, communications, and radionavigation sources and their excellent spatial coverage gives great scope for PBR. In common with all bistatic radars, it may allow mechanisms such as forward scatter, which enhances the radar signature of targets, to be exploited. The fact that PBR systems can be simple and low cost has meant that they have been very suitable for research by university groups, and there have been numerous publications on the subject.
