The invention discloses a static target restraining method for a ground surveillance 
radar system. The static target restraining method for the ground surveillance 
radar system comprises the steps that processed target detection information of the front end of a 
radar is obtained; interframe accumulation 
processing is carried out on the target detection information, and a two-dimensional image isformed according to the target detection information after the accumulation; 
edge extraction is carried out on the two-dimensional image, and target detection information which belongs to a same target after the extraction is obtained; static target area judgment 
processing is carried out on the target detection information which belongs to the same target, and a static target area range is markedout; and restraining 
processing is carried out on the target detection information in the static target area range, and target detection information after the static target restraining is obtained. According to the static target restraining method for the ground surveillance radar 
system, the problem that the ground surveillance radar system cannot accurately mark off the static target area due to variation of detection scenes and erecting sites is solved, the restraining speed of a static target and the detection precision of a moving target are improved, and a reliable data foundation is provided for subsequent track processing.
