雷达与双波段红外探测器融合跟踪系统

利用双波段红外探测系统测到的目标双波段红外辐射信息,推导出目标的伪距离量测信息,使得单站红外探测系统变为可观测系统;在此基础上,采用带反馈的分布式估计融合算法,将雷达与双波段红外探测系统得到的局部航迹进行融合,并将每次融合估计的结果反馈给局部传感器,使得融合中心达到最优性能的同时,减小了雷达和红外局部估计的误差.仿真结果表明:①单站红外探测系统利用目标的双波段红外辐射信息能够对目标进行有效地跟踪,跟踪精度较高;②带反馈的布式估计融合算法具有良好的跟踪性能,而且能够明显改善局部传感器的跟踪精度.

The Fusion and Tracking System Based on Radar and Infrared Sensor with Dual Bands

By using the infrared radiation information of the target observed by infrared sensor with double bands,the pseudo-range information of the target is deduced and it causes infrared sensor with double bands in single observer becomes to be observable.Furthermore,the distributed fusion algorithm with feedback in fusion center is chosen to fuse the tracks from radar and infrared sensor with dual bands.After every fusion is finished,the results of fusion is sent back to radar and infrared sensor and that makes the tracking performance of the fusion center to be optimal and the estimate errors of radar and infrared sensor to be reduced.The simulation results show that single infrared sensor with dual bands can track effectively target by using the infrared radiation information of the target,and the fusion algorithm with feedback has not only better performance of target tracking,but also can improve obviously the tracking performance of radar.
