实际应用的波达角估计算法主要有最大似然估计、比幅和超分辨等。文中在深入分析这些算法的基础上，提出了一种新的角度估计算法，称之为相关角度估计算法。理论研究和仿真分析表明：相关角度估计算法更易于工程化，相对于比幅法有更高的角度估计精度，比最大似然估计具有更小的计算量，比超分辨测角估计更高，计算量更小。

At present, the actual application of the DOA estimation algorithms includes maximum likelihood estimation, amplitude angle measurement, super-resolution angle measurement and etc. On the basis of an in depth analysis on these algorithms, this paper proposes a new angle estimation algorithm, which is called the correlation angle algorithm. Theoretical researches and simulation analyses show that the correlation angle algorithm is easier for engineering, more accurate than amplitude angle measurement and less complex in calculation than maximum likelihood estimation.in addition, compared with super resolution angle measurement, it is higher in the estimated value and smaller in the amount of calculation.
