摘要
为了有效应对强噪声干扰、箔条干扰以及红外诱饵干扰,提出了一种雷达/红外复合导引头抗干扰跟踪方法。该方法通过导引头观测信息关联度的检测、新息方差迹值的比较,进而对干扰进行判断,然后选择合适的导引头工作模式对目标进行跟踪。仿真结果表明,所提出的协同跟踪方法不仅可以保证较高的跟踪精度,而且可以保证在干扰环境下对目标跟踪的连续性与稳定性。
For resisting the strong noise jamming,chaff jamming and infrared decoy jamming,this paper puts forward the radar/infrared dual-mode seeker cooperative anti-jamming tracking method. Judge the jamming and then select the proper seek operating mode to track the target by detection of the information correlation for the seeker and comparison of information variance. The simulation result shows that the method could not only guarantee tracking accuracy,but also the stability and continuity of target tracking could be guaranteed in anti-jamming environment.
