Evaluating the Performance of FM-Based PCL Radar in the Presence of Jamming

In this paper, we examine an FM-based passive coherent location (PCL) radar system and attempt to quantify its performance in the presence of various different jamming waveforms namely broadband noise and a single tone on the carrier. It is shownthat effective jamming can be achieved with relatively low jamming power. The importance of an effective direct signal canceller is also shown as a means of suppressing the jamming signal. The effect of these jamming scenarios is shown through simulation and then compared to a representative measured result from a real FM-based PCL radar system.
