在多传感器跟踪系统中,由于通信时间延迟等原因,常常出现各传感器对同一目标的测量不能按照正常顺序到达数据处理中心的情形,使其出现了所谓的无序滤波问题。为此介绍了工程上经常采用的4种无序滤波算法,并给出了仿真结果。

In multisensor tracking system,there are usually different time delays in transmitting the data from various sensors to data processing center.This can lead to situations when measurements from the same target arrive out-of-sequence.This results in the problem of out-of-sequence filtering.So four algorithms for out-of-sequence filtering are proposed,and simulation results are also presented in this paper.
