Abstract: FM based passive radar faces some issues such as time varying bandwidth and RCS glint, a multiple FM joint detection scheme is proposed, and the corresponding experiments with passive radar system developed by Wuhan University are carried out. First, the process flow of multi-FM based Passive Radar is introduced. Then, the signal characteristics of multi-FM for radar application are analyzed, meanwhile, the necessity and advantages of multi-FM scheme are demonstrated. Finally, the practical processing results are presented. Experiment result proves that multiple frequency detection scheme can substantially improve target detection performance, enhanceing the robustness of passive radar system.
