摘　　要：为研究末制导跟踪阶段雷达导引头的波形选择,提出了一种认知雷达导引头制导跟踪过程中的波形选择算法。首先,结合导引头制导和观测滤波模型,建立了雷达导引头波形选择的处理流程;其次,使用交互式多模型无迹卡尔曼滤波(IMMUKF)算法来解决非线性跟踪问题;基于最大互信息准则搜索波形参数使得跟踪误差最小。仿真结果表明,波形选择算法可以有效提高导引头跟踪精度,并提供更为平稳的制导过载。In order to study the waveform selection of radar seeker in the terminal guidance and tracking phase,this paper proposes a waveform selection algorithm in the guidance and tracking process of cognitive radar seeker.Firstly,we establish the processing flow of radar seeker waveform selection by combining the seeker guidance and observation filtering models;Secondly,we use the interactive multiple model unscented Kalman filter(IMMUKF)algorithm to solve the nonlinear tracking problem.We minimize tracking error by searching for waveform parameters based on the maximum mutual information criterion.The simulation results show that the waveform selection algorithm can effectively improve the seeker tracking accuracy and provide stable guidance overload.
