无源定位系统的快速航迹起始算法

航迹起始是多目标跟踪过程中面临的首要难题。基于无源定位的特点，提出了一种适用于无源定位系统的快速航迹起始方法，即航迹搜索法。这种方法首先用速度法建立可能航迹，然后利用自适应相关门技术对后续的量测集进行相关，搜索出属于该可能航迹的所有点迹后再进入下一循环搜索新的航迹。实际数据的检验结果证明了这种方法的有效性。

Fast Track Initiation Algorithm for Passive Location System

Track initiation is the key problem of multi-target tracking. Based on the characteristic of passive location, a new method for track initiation is presented. In this new method, velocity method is used firstly to find possible track, an adaptive association gate is adopted to associate with successive measurements. Search of the next track will not be performed until all measurements that belong to this possible track are searched. The rest track may be found as the same search method. Simulation results demonstrate the performance of this algorithm.
