| 摘 要： | 本文提出了一种新的DOA(direction of arrival)估计方法,通过对信号子空间进行抽取,形成信号子空间的两个子集,由于两个子集包含有来波方向信息,采用最小二乘算法,能估计出信号的DOA。该方法的分辨性能和LS-ESPRIT算法的性能相当,但运算量比LS-ESPRIT以及MUSIC的要小很多。计算机仿真试验证实了方法的有效性。

| Abstract: | A novel method of estimation DOA has been proposed in this paper, formed two subsets by extracting the signal subspace, because of including signals in- formation, using Least Square arithmetic, the DOA of signal can be estimated from the subsets. The method has the same resolution as the LS-ESPRIT, but it need less computation compared with MUSIC and LS-ESPRIT. Computer simulation confirms the methods availability. |
