摘要
在多传感器信息系统中,来自不同传感器的局部航迹往往是异步的,针对此问题,提出了一种基于伪点迹的异步航迹关联算法。首先利用点迹重构技术将异步航迹进行时间对准,然后再利用经典分配的方法对各局部航迹进行了配对,从而达到异步航迹关联的目的。仿真结果证明此方法能很好地解决多传感器异步航迹关联的问题,关联正确率接近90%。
In the multi-sensor information system, the local tracks from different sensors are always asynchronous. To solve the problem, this paper presented a multi-sensor asynchronous track association algorithm. First, the technology of pseudo measurement is used to synchronize tracks. Then local tracks are assigned by using classical assignment algorithm. The simulation result illustrates that this new algorithm can solve the problem of asynchronous track association effectively, and the association correct rate approaches 90%.
