首先分析了红外诱饵干扰、雷达拖曳式、箔条干扰等典型干扰对毫米波雷达/红外融合跟踪系统的影响,然后在此基础上对目标释放各种干扰的行为进行分析,进而实现干扰事件的判别,最后融合中心根据干扰事件自适应的选择融合算法实现对目标的跟踪.通过仿真实验表明:本方法可以准确地实现对干扰事件的判断,并且能够提高在干扰存在的情况下目标跟踪精度.
Firstly, the influences of typical infrared jamming, radar towing and chaff jamming on the millimeter-wave radar / infrared fusion tracking system are analyzed. Based on this, the behavior of various interferences released by the target is analyzed, and then the interference events Finally, the fusion center realizes the tracking of the target according to the adaptive selection fusion algorithm of the interference event.The simulation results show that this method can accurately judge the interference event and improve the target tracking accuracy in the presence of interference.
