In response to the problem of passive detection of maritime targets,the passive bistatic radar(PBR)system was used to conduct research on passive maritime target detection.A series of real-time outfield experiments on maritime target detection were conducted,and some I/Q data were successfully collected and system display diagrams were drawn.In this paper,the working principle of the PBR system is introduced,and then the signal processing process is described in detail,including reference signal reconstruction,pulse compression,direct wave suppression,non-cohe-rent accumulation,and MTI/MTD moving target processing.Finally,the outfield experimental results are introduced and the obtained experimental data are analyzed.Experiments show that this system can achieve passive coherent detection of maritime targets.
