摘要
摘要:航迹起始是群目标跟踪的首要环节，其性能好坏直接影响着目标跟踪航迹的质量。传统的群目标航迹起始方法仅利用目标的位置信息完成分群检测和等效量测求解等步骤，没有充分利用回波幅度信息，存在分群检测不理想、等效量测求解不准确等问题，有可能引起失跟现象。针对此问题，该文提出一种回波幅度信息辅助的群目标航迹起始方法。首先利用目标位置信息和幅度信息完成分群检测，然后综合采用幅度加权和位置加权求解等效量测，最后基于修正的逻辑法进行群目标航迹起始。该文方法在分群检测和求解等效量测等步骤充分利用了回波幅度信息，不仅可以在集群数量未知的情况下正确划分群，而且降低了失跟率，提高了群目标的跟踪性能。仿真结果验证了所提方法的有效性。

Abstract:Track initiation is the first important step in group target tracking, and it has a direct effect on the quality of the overall procedure. Traditional radar target tracking methods only utilize information about the target position to detect group numbers, but they do not use information relating to echo amplitude. Tracks are thus easily lost, as the numbers of detected groups and equivalent measurements are inaccurate. This paper proposes a group target track initiation method aided by echo amplitude information to ameliorate these problems. In this respect, target position and echo amplitude information is used to detect the number of target groups, and equivalent measurements are then computed using amplitude weighting and position weighting. Echo amplitude information is employed in the step of detecting group target numbers and computing the equivalent measurements, and group target tracks are subsequently initialized using the modified logic method. The proposed method can be used to correctly detect the number of target groups when the number is previously unknown. Furthermore, the method reduces the rate of track loss and improves the performance of group target tracking. The effectiveness of the proposed method is validated by the simulation results.
