| 摘 要： | 本文基本三个阵列空间的排列组合提出了一种新的多个空间信号频率和2－D到达方向的估计方法。由于该方法是将问题转化为三个1－D问题且在每一维利用计算有效的ESPRIT算法和利用子阵列的输出数据矩阵具有相同的列空间，因此避免了多维谱估计中的谱峰搜索和参数间的配对。计算机模拟实验证实了其有效性。

| Abstract: | Based on permutation and combination of three subarrays in space, a new method for estimatingmultiple spatial signal frequencies and 2-D directions of arrival is proposed. With decomposing the problem into three 1-D estimation problems and using computional efficient ESPRIT algorithm in each direction, thus theproposed method gets rid of the costly 3-D spectral peak search needed by conventional 3-D spectral estimation, By means of subarray output data matrices ooning the same column space, the estimated parameters arepaired automatically. Computer simulation confirms its effectiveness. |
