Abstract: For the target-tracking using active sensor and passive sensor with asynchronous sampling frequency, a new decoupled algorithm is proposed. On the sampling time without distance measurement, the tracking filter is processed by making up virtual measurement point. Because all the angle measurement information is effectively utilized by the algorithm, the performance of tracking filter is elevated. Simulation results show that the algorithm has high tracking precision and its computational cost is smaller.

摘要： 针对主动传感器与被动传感器采样频率不相同的目标跟踪问题，提出一种新的解耦算法。在没有测距信息的采样时刻，通过构造虚拟量测点的方法进行滤波跟踪，有效地利用了全部测角信息，提高了跟踪性能。仿真实验表明，该算法具有较高的跟踪精度，且只占用较小的时间花费。
