| 摘 要： | 提出了一种利用空间谱估计对干涉测角系统进行解算的方法,该方法在多重信号分类(M USIC)算法的基础上,对协方差矩阵的估计、特征值分解、谱峰搜索等计算量较大的步骤进行了改进,提高了运算速度.并根据入射角连续的特点,提出了空域跟踪搜索的算法,进一步减小了计算量,同时提高了解模糊的正确率.

| Abstract: | A method using the spatial spectrum estimation for the resolution of the angle measurement with interferometer is proposed.The method improves the computationally intensive steps of the MUSIC algorithm to speed up its computation.The steps include the estimation of the covariance matrix,the eigendecomposition and the spectral peak searching.Based on the feature that the direction-of-arrival is continuous,a spatial track searching algorithm is proposed.The computation consuming is father reduced and the ambi... |
