点迹/航迹关联是多传感器数据融合系统的关键问题.为提高关联的正确率,把红外传感器方位数据与雷达数据进行关联,通过红外高精度的角度测量和雷达高精度的距离测量的融合,减小系统融合航迹同真实航迹间的误差,给出对目标航迹的精确状态估计.分别讨论了雷达数据的航迹关联算法和雷达/红外数据的航迹关联算法,并进行了仿真性能比较和分析.

Plot-track association is the most important part in multi-sensor data fusion system. To improve the correct association rate, the infrared sensor is taken into the fusion system. The angle of infrared with high accuracy is fused with the range of radar with high accuracy. Thus the discrimination between the fused track and the real track becomes smaller and the accurate status estimation of the target is obtained. The algorithms for radar data association and for radar/infrared data association are discussed. The simulation is made to compare the performance of the two algorithms.
