针对由雷达和红外传感器组成的异类传感器数据融合系统中的多目标航迹相关问题,提出了基于灰色关联分析的异类传感器航迹相关算法.该算法将目标航迹看成是方位信息的时间序列,所有目标航迹构成方位时间序列集合,利用B型关联度对该集合元素进行灰色关联分析,形成航迹灰色关联度矩阵,采用最低关联度门限与全局最优的策略确定航迹关联对,实现异类传感器纯方位航迹相关判定.仿真试验结果表明:该方法能解决由雷达和红外传感器组成的异类传感器航迹相关.
Aimed at the problem of multi-target trajectory correlation in heterogeneous sensor data fusion system composed of radar and infrared sensors, a trajectory correlation algorithm of heterogeneous sensor based on gray relational analysis is proposed. The target trajectory is regarded as the time series of azimuth information , All the target trajectories constitute the azimuth time series set, and the gray relational analysis of the set elements is carried out using type B correlation degree to form the track gray relational degree matrix. The track association pairs are determined by using the lowest relevance threshold and the global optimum strategy, The result of simulation test shows that the method can solve the track-related correlation of heterogeneous sensors composed of radar and infrared sensors.
