摘要
针对非合作双基地雷达系统的特点,提出了一种能快速找到航迹的目标跟踪处理方法。该方法首先用基于速度的方法起始可能航迹,然后利用跟踪波门技术对后续的测量点集进行相关性检测,接着进入Kalman方法预后续点迹位置的阶段,然后用最近邻域(NN)法搜索出属于该可能航迹的所有点迹,最后进行航迹的确认并开始搜索新的目标航迹。以实测数据为例进行实验,验证了该方法对非合作雷达系统目标跟踪的有效性。
According to the characteristic of passive radar,a new method of multi-target track processing based on kalman filter track is presented. In this method,approach based on velocity rule（ as formula 17） is used firstly to find possible track,an adaptive association gate is adopted to associate with successive measurements,then use Kalman filter to predict locations of successive measurements,nearest neighouring method is used to search all points belong to the possible track and finally confirmed track and go to the next cycle to find new target track. Experiments with real data were compared to traditional EKF,the valid performance of this approach is verified.
