| 摘 要： | 为了获得高精度的多输入多输出（multiple-input multiple-output,MIMO）雷达的目标角度估计和幅度估计,本文基于幅度相位估计（amplitude and phase estimation,APES）算法和广义似然比检验（generalized-likelihood ratio test,GLRT）算法,提出了一种使用似然比的相位幅度估计（GAPES）新算法。在接收端通过GLRT算法估计出目标角度,然后用APES算法修正幅度,实现了在强干扰环境下提高角度和幅度分辨率。仿真结果表明了该算法的有效性。

| Abstract: | In order to obtain better performance for angle and amplitude estimation of Multiple-Input Multiple-Output（MIMO） radar,a new algorithm（GAPES） based on Amplitude and Phase Estimation（APES） algorithm and Generalized-Likelihood Ratio Test（GLRT） algorithm is presented in this paper.Firstly,the angles of the targets can be estimated separately at the receiving side by the use of GLRT algorithm.Then amplitudes of the targets are corrected by the use of APES algorithm.The proposed algorithm provides better angle and amplitude resolution in strong interference environment.The simulation results demonstrate the validity and superiority of the proposed algorithm. |
