Abstract

The invention discloses a target extraction method based on a ground surveillance radar system. The method comprises the following steps of: obtaining target echo information processed by the front end of a radar; performing a false plot filtering process on the target echo information; performing a fuzzification process on the target echo information after the false plot filtering process; forming a two-dimensional image on the target echo information after the fuzzification process, and performing target edge extraction on the two-dimensional image; performing ground object target filteringprocess on the obtained target echo information which belongs to the same target after the edge extraction; and obtaining the target echo information which belongs to the same target after the groundobject target filtering process. According to the target extraction method based on the ground surveillance radar system, the target extraction integrity is improved, the target extraction precision is improved, and the risk that the same target is split into multiple targets when performing target extraction is reduced.
