Problems solved by technology

[0004] The traditional target aggregation method uses the one-dimensional detection and merging method of condensing in the distance direction first and then the azimuth direction, without considering the speed of the target, which reduces the speed resolution ability of the target, resulting in merging targets with different speeds into the same a goal

Abstract

The invention discloses a target clustering method based on a ground surveillance radar system. The method comprises the following steps of acquiring target echo information after radar front-end processing; carrying out false plot filter processing on the target echo information in order to obtain filtered target echo information; carrying out speed clustering on the filtered target echo information in order to obtain target echo information after speed clustering on a distance library; carrying out distance clustering on the target echo information after speed clustering on the distance library in order to obtain target parameters and target echo information after distance clustering at the azimuth; and carrying out azimuth clustering on the target echo information after distance clustering at the azimuth in order to obtain target parameters and target echo information which belong to the same target after azimuth clustering. According to the method, the risk that the targets at different speeds are merged into the same target is reduced, the precision of target clustering is improved, and a reliable foundation is provided for follow-up track processing.

Description

technical field [0001] The invention relates to the technical field of real-time target aggregation of a ground surveillance radar system, in particular to a target aggregation method based on a ground surveillance radar system. Background technique [0002] Ground Surveillance Radar System is a short-distance detection system that uses radar reconnaissance, photoelectric identification and tracking. Under the background of ground objects, it can detect, track and manage ground vehicles, pedestrians, water vessels and airborne aerodynamic vehicles. [0003] Among them, target agglomeration is to combine the target echo information belonging to the same target into one target echo information, so as to reduce the burden of radar data processing and improve the track tracking quality. Therefore, choosing the optimal agglomeration method is crucial to the subsequent process of accurately estimating the target parameters. [0004] The traditional target aggregation method uses...
