Modeling and characteristics analysis of clutter for passive radar on moving platform

摘要

In the latest years, the investigation of passive radar on moving platform (PRMP) for surveillance purpose has received a new interest. The problem of direct path interference and ground (sea) clutter is encountered in PRMP. This paper studies the modeling and characteristics of the clutter in PRMP which employs digital radio and television illuminators based on Single Frequency Network (SFN) configuration. The clutter model of PRMP is established firstly, and then the space-time characteristics are elaborately analyzed. The experiment performed with the newly-developed multi-channel passive radar system validates the correctness of the proposed model. The study provides the underlying theory for clutter suppression and target detection in PRMP.
