Exploitation of Deterministic Signals for Passive Single-Channel Detection

Passive Bistatic Radar (PBR) systems use non- cooperative illuminations of opportunity to detect, localise and track targets. The aim of this paper is to investigate the potential of PBR target detection in the presence of non-random signals emitted by non-cooperative transmitters of opportunity, such as radar systems, and without the use of a reference channel. An experiment to detect a moving target was carried out at the Defence Academy of the United Kingdom to demonstrate target detection capabilities using a low cost off-the-shelf receiver. Results show that moving targets can be successfully detected although care must be taken in correcting for frequency offset effects deriving from the non- coherency and non-stability of the receiver local oscillator.
