摘要
在分析了编队目标跟踪现有的K-方法和集群引晶方法的基本原理、步骤及存在问题的此基础上,针对编队目标不同于一般多目标的特点,提出了基于相控阵雷达的编队目标重心跟踪方法。该方法根据监视区域内多目标回波的空间距离进行编队分离检测预处理,以形成编队目标。在完成分群检测后,再利用目标回波幅度信息求解每个编队目标的重心,以编队目标重心为等效量测实现编队目标跟踪。仿真结果证明了该方法的正确性与有效性。
Formation-target tracking is special comparing with ordinary muhi-target tracking. A method is proposed for formation- target barycenter tracking based on phased-array radar. The steps and basic principles of K-means and cluster-seeding method for for- mation-target tracking are analyzed. First, all echoes in the surveillance space are determined by formation separation detection. Then, the barycenter of each formation-target is calculated by the amplitude of the target-echo. At last, the equivalent echo of the formation- target and its barycenter are found, then data-association is performed. Simulation shows the efficiency of the method for formation-tar- get tracking.
