However, the three subaperture algorithm is very efficient to deal with the problem.

而三子孔径算法是针对该难题而提出的一种有效算法。

Base on the maximum likelihood algorithm, the algorithm divides an array into three subaperture and predigests the estimate function and reduces the compute quantity.

此算法基于极大似然算法将等距线阵均分为三个子孔径，从而简化了估计函数，也使计算量大大减少。
