摘要:

当一个或者2个正交方向存在相同的空间相位因子时,常规的波达角估计算法无法进行有效的DOA估计并导致估计性能下降。在DOA矩阵法的基础上,采用了联合对角化技术实现二维波达方向(2D DOA)估计。该方法不但能够实现估计值的自动配对,而且能够更有效地克服现有算法中由于出现相同空间相位因子而导致估计性能下降等问题。仿真实验证明了该方法的有效性。

Abstract:

When space phase factors are the same in one direction or two orthogonal directions,the convensional direction-of-arrival methods cannot estimate DOA effectly,resulting in performance degradation.Therefore,joint diagonalization technique was utilized to estimate two-dimensional (2D) DOA on the basis of DOA matrix method.This technique can not only achieve automatic pairing of estimated DOA,but also effectively resolve the performance degradation when the space phase factors are the same.The simulation results show the effectiveness of the technique.

Key words: array signal, extended-aperture, direction-of-arrival, automatic pairing
