摘要
由于双基地机载雷达体制下载机间存在相对运动,导致双基地机载雷达的配置情况处于时变状态。首先建立了双基地机载雷达的杂波仿真模型,然后在此基础上利用MATLAB软件仿真得到不同配置情况下的双基地机载雷达的杂波空时二维分布轨迹以及杂波特征谱,最后通过深入地分析得到了双基地机载雷达杂波呈现严重非均匀性和杂波自由度增加的重要结论。
Due to the relative motion between the receiver and the transmitter,the bistatic configuration may vary with time,Based on a two dimensional space-time clutter model,the simulation results of the iso-doppler and iso-cone distribution and clutter space-time spectrum trace under different configurations were proposed.Finally,some important conclusions were achieved about the nonstatioarityof clutter and the increase of clutter DOF of bistatic airborne radar.
