摘要
在复杂的实战环境中,雷达的先验信息具有很大的不确定性,且由于干扰更加智能化,导致实战中雷达的探测性能再度降低。为提高电子战雷达的探测性能,提出了一种基于互信息与信干噪比加权准则的雷达博弈波形设计方法。首先建立了互信息和信干噪比的加权准则,然后设计相应的雷达与干扰博弈模型,最后提出最大边缘重分配算法以解决重复博弈困境,精炼纳什均衡。仿真实验验证了该方法的有效性。
In the complex actual combat environment,the uncertainty of the prior information of the radar makes it difficult to meet the performance requirements,and the interference is more intelligent,which further reduces the detection performance of the radar in actual warfare.In order to improve the detection performance of electronic warfare radars,a radar game waveform design method based on mutual information and signal-tointerference-plus-noise ratio weighting criterion is proposed.First,weighting criterion for mutual information and signal-to-interference-plus-noise ratio is established,and then the radar and jamming game model based on the above criterion is designed.Finally,the maximum marginal reallocation algorithm is proposed to solve the repeated game dilemma and refine the Nash equilibrium.Simulation experiments verify the effectiveness of the proposed method.
