摘　　要：为确定航迹，针对多传感器目标跟踪系统提供的大量信息，通过对原始数据的分析以及定义相关的参数，详细研究了雷达航迹的搜索问题。使用逻辑法进行航迹起始搜索，并提出了两个新的概念：动态波门和加速度距离，提高该方法的合理性。动态波门的使用提高了检测概率，减少虚警，加速度距离作为二次筛选以确保多个航迹和下一时刻的多个观测点之间的一一对应，能很好地确定航迹。该结果为多个雷达之间航迹的融合以及对复杂航迹的预测提供参考。In order to find out the flight path through a large number of data from multi-sen- sor target tracking system, the initial data are analyzed, the relative coefficients are defined, and the flight path searching problem with radar is deeply researched. The logic method is used to carry out the intial search of flight path. There are two new concepts proposed, dy- namic wave gate and acceleration distance, which make the method more reasonable. Dy- namic wave gate can be used to raise the test probability and reduce fake alarm. Acceleration distance can be used as the second screen to ensure the one-for-one maps between different flight paths and next time observed data points. The results can offer reference for flight path confirming from different radars and complicated flight path forecast.
