一种新的雷达与红外传感器异平台数据融合方法

New data-fusion algorithm for radar and IR sensors at different sites

针对现有雷达与红外传感器异平台数据融合算法定位精度不高的现状,直接采用由雷达位置与雷达量测的目标距离确定的圆和由红外位置与红外量测的目标方位确定的直线相交,对目标进行定位,提出了一种新的雷达和红外传感器位于异平台情况下的数据融合算法,减小了雷达角度测量误差对定位结果的影响。仿真分析证明新的融合算法与现有融合算法相比有效地提高了目标定位精度。

Aiming at the problems lying in the present fusion algorithms for hererogeneous sensors at different sites, a new data fusion algorithm is proposed for radar and IR sensors at different sites based on the accuracy of the distance measurement of radar and angle measurement of IR sensors. In the algorithm, a circle determined by the location of ra- dar and distance measurement of radar intersects the line determined by the location of IR and angle measurement of IR. The intersection point is the location result. Comparisons of simulation results show that the new algorithm can improve the target location precision greatly.
