摘要
分析了MIMO雷达和无源雷达特点,建立了基于FM广播的无源MIMO雷达系统模型,基于奈曼-皮尔逊(Neyman-Pearson)准则分析比较了MIMO雷达和相控阵雷达的探测性能,并给出了仿真研究结果。MIMO雷达的分集增益,能有效得克服目标闪烁引起的RCS的波动和多径干扰,提高目标的检测概率。文中的研究工作为改善无源雷达探测性能进行了有益的探索。
The MIMO radar and the passive radar characteristics are analyzed.Then the passive MIMO radar signal model based on FM broadcast is established.The detection performance is compared between MIMO radar and the phased-array radar with the Neyman-Pearson criterion.The simulation results are presented.The MIMO radar diversity gain can overcome effectively the RCS fluctuations caused by target scintillations.The probability of detection is enhanced.This research should be beneficial for the improvement of passiv...
