摘　　要：针对无源定位系统定位误差大、数据更新率不规则等问题,研究了一种通过定位数据辅助信息特征进行多目标航迹融合的新方法。该方法利用信号侦察获取的目标辅助信息作为航迹关联判决准则,并与传统的航迹关联方法相结合,从而实现了对侦察区域内多目标的航迹融合。对该算法的性能分析和仿真验证表明,新算法具有更好的航迹融合性能,更强的通用性和可扩展性;并且在密集多目标环境下可实时、有效地跟踪几十批次的目标。Aiming at the problems such as the big location error and irregular data renew rate in the passive location system,a new method for multi-target track fusion is studied in this paper by means of the location data assistant information characteristics.The method makes use of the target assistant information obtained from signal reconnaissance as the decision rule of track association,and is combined with traditional track association methods,resulting in multi-target track fusion in the reconnaissance region.The performance analysis and simulation verification to the algorithm show that the new algorithm has better track fusion performance,stronger universality and extensibility;and it can effectively track tens batch targets in real time in the dense multiple-target environment.
