摘　　要：在密集杂波点迹区域,传统点迹过滤方法易出现目标检测跟踪丢失现象。根据目标的时空相关性和运动轨迹唯一性,提出了一种基于时间前后向误差的杂波点迹检测方法。该方法通过计算前向搜索和后向搜索2条轨迹的欧氏统计距离,实现了杂波点迹的识别和过滤。最后,蒙特卡罗仿真分析和实装数据验证表明,该方法可提高杂波点迹过滤正确率,且未出现低信噪比目标点迹丢失现象,从而提升了点迹过滤性能。In dense clutter plot region,traditional plot filtering method easily lead to loss detection and tracking.According to the target′s characteristics of spatial-temporal correlation and unique trajectory,a clutter plot detecting method based on forward-backward error is proposed.In the method,by calculating the Euclidean statistical distances of forward search and backward search trajectories,clutter plot can be identified and filtered.Finally,Monte Carlo simulation analysis and real data validation show that the method can improve the accuracy of clutter plot filtering,and there is no loss tracking phenomenon of target′s low signal-to-noise ratio plots.Thus,the method can improve the performance of plot filtering.
