摘要
为了克服航迹关联过程中传感器系统误差和随机测量误差的影响,提出了一种二维航迹关联方法。该方法建立了同一时刻不同传感器观测同一目标的位置差距与系统误差、随机测量误差间的函数关系,并通过计算位置差距的范围设立第一维的关联门限,然后通过计算连续时刻内位置差距的方差范围建立第二维的关联门限。仿真结果表明,相对于传统的双门限法,该方法对多传感器数据进行关联,具有较高的正确率。
In order to overcome the influence of sensor system error and random measurement error in correlation process, this paper presents a two-dimensional track correlation method. The method establish functional relation to explain the influence of sensor system error and random measurement error on position difference between tracks which are formed by one target in different sensors. The first threshold is established based on the range of position difference. And the second threshold is formed based on the range of variance for position difference of a sequence in continuous moments. Simulation results show that the method has higher correct correlation rate than traditional double-threshold correlation.
