将硬约束自适应波束形成技术，用于高分辨方位估计主要是在“空间平滑”方法的基础上，用克莱姆—施密特修正递归误差反馈（ＲＭＧＳＥＦ）算法来代替ＬＭＳ算法，对相干信号进行高分辨力处理并通过计算机模拟和海试数据的处理，对这种算法进行研究结果表明：在高信噪比的条件下，ＲＭＧＳＥＦ算法比ＬＭＳ算法有很大的优越性再加上ＲＭＧＳＥＦ算法所具有的并行流水线的处理结构，这就为在实际上得到应用创造了条件 The hard constraint adaptive beamforming technique is applied to high resolution DOA estimation. The LMS algorithm is replaced by the Crams-Schmidt Modified Recursive Error Feedback (RMGSEF) algorithm based on the “spatial smoothing” method. The results show that RMGSEF algorithm has more advantages than LMS algorithm under high signal-to-noise ratio.  Together with the parallel pipeline processing architecture that the RMGSEF algorithm has, this creates the conditions for actually getting the application
