| 摘 要： | 在异类传感器信息融合系统中,快速准确地对目标进行数据关联极为重要.为解决2D雷达与红外传感器在三维空间中的数据关联问题提出了一种新方法.该方法采用两级关联算法进行关联,首先利用精度较高的2D雷达径向距离和红外传感器俯仰角及方位角找出目标在X-Y平面上的可能位置,通过构造角度检验统计量完成第一级关联,排除大部分虚假定位点；再采用二维分配算法对余下的候选关联组合进行精确关联,从而获得最优关联分配方案.仿真结果表明该方法较大地提高了正确关联概率,是一种有效实用的数据关联方法.

| Abstract: | Fast and precise data association method plays an important role in the heterogeneous sensor information fusion system.In order to solve the typical problem of data association encountered in three-dimensional heterogeneous sensor system with 2D radar and IRST,a new method with two steps is presented.Firstly,the accurate azimuth and elevation of IRST and radial distance of 2D radar are used to obtain possible position in two-dimensional coordinate,and angle statistics is constructed to eliminate most false ... |
