An algorithm for matching the esprit ' s estimation of two - dimensional angle by using twice svd and once schur is proposed . using two row uniformity sensor - arrays and adding one sensor , the algorithm decomposes the array twice and exploits rotational invariance properties of signal space , so that both angles may be computed via matrix pencil method , and these estimates are automatically paired . simulation results are presented to verify the efficacy of the proposed algorithm
首先针对esprit算法对窄带源进行二维doa估计存在测向冗余的情况，提出了一种改进算法，该算法利用子阵信号数据矩阵中包含的信号空间的旋转不变性质，借助于矩阵束方法求解出信号的二维到达角，并且利用两次奇异值及一次schur分解从而实现了esprit二维doa估计参量的自动配对； 2
