寻的制导雷达在电子干扰条件下可能测得错误的距离信息,以切换系统模型来描述此问题,并提出了一种新的多模型跟踪滤波器来实现制导信息的估计。该滤波器分两步序贯处理角度测量和距离测量数据,从而有效地改进了距离测量修正中的线性化参考点。仿真结果表明,这种估计方法使得距离测量正确情况下的滤波精度得到提高,并且能以很高的概率消除错误的距离测量数据对滤波的影响。
Guided radar can detect the wrong distance information under the condition of electronic jamming, switch the system model to describe this problem, and propose a new multi-model tracking filter to realize the guidance information estimation. The filter processes angle measurement and distance measurement data in two steps, which effectively improves the linearized reference point in distance measurement correction. The simulation results show that the proposed method can improve the filtering accuracy under the condition of correct distance measurement and eliminate the influence of false distance measurement data on the filtering with high probability.
