摘要 提出了一种基于传播算子的低复杂度二维波达方向估计新算法,该方法避免了常规子空间方法中占主要运算量的估计信号协方差矩阵及其高维矩阵的特征分解,降低了运算复杂度,并且由于无阵列孔径损失,获得了良好的参数估计性能。最后计算机仿真验证了算法的有效性。 Based on the propagator method, a low complexity method for estimating 2-D DOA is presented. The new method avoids the estimation and eigendecomposition of the covariance matrix of the received signals which is the main computational burden in traditional subspace method. This algorithm achieves good performance without the aperture loss. The effectiveness of the proposed algorithm is verified by computer simulations in the end of this paper.
