摘要
基于矩阵填充的阵列信号均匀空间采样方法可以减少采样通道数目,降低系统硬件实现成本。结合子空间分解类算法给出了基于均匀空间采样模型的矩阵填充DOA估计方法,并通过数值仿真验证了该算法的有效性。
Uniform spatial sampling method for array signals based on matrix completion can reduce the number of sampling channelsand the realization cost of system hardware.Combiningwith subspace decomposition algorithm,a new method----matrix completion direction of arrival(DOA)estimation algorithm based on uniform spatial sampling model is proposed in this paper,and simulation results verifies that the proposed algorithm s effective.
