ESPIRT算法的matlab仿真，基于旋转因子不变形doa估计算法。只适用于均匀线阵。-ESPIRT algorithm matlab simulation, based on the rotation factor is not deformed doa estimation. Applies only to uniform linear array.

几种算法实现DOA，有经典MUSIC算法，Root-MUSIC算法，ESPIRT算法等比较实现了对目标到达角度的估计。-Several algorithm DOA, classic MUSIC algorithm, Root-MUSIC algorithm, ESPIRT comparison algorithm to achieve the estimated target angle of arrival.
