| 摘 要： | 提出了一种快速ＥＳＰＲＩＴ算法，使用该算法和两平行均匀线阵可实现二维来波方向的快速估计，快速ＥＳＰＲＩＴ算法复协方差矩阵中不受噪声影响的子块来估计来波方向，避免估计整个协方差矩阵和噪声功率，减少了特征分解的次数，大幅度地降低了运算量，而参数的估计性能接近ＰＲＯ－ＥＳＰＲＩＴ算法，最后给出了计算机仿真结果，表明了该算法的有效性。

| Abstract: | A fast ESPRIT algorithm is proposed. 2D DOA estimation is obtained using uniform parallel array and this new algorithm. The algorithm uses the sub block of covariance matrix which is not affected by noise to estimate the parameters of DOA. No estimations of whole covariance matrix and noise power are required, and the times of SVD are decreased, so the cost of its computation is decreased. The performance of the algorithm is near to that of PRO ESPRIT but with lower computational cost. Finally the numerical simulation results are presented to illustrate the efficiency of the algorithm. |
