阵元缺损下的波达方向估计算法
A Novel DOA Estimation Algorithm in Conditions of Array Elements Deficiency
摘要
Abstract
In order to solve the accuracy decrease in angle estimation caused by the undersampling or the damage of the array elements in the uniform linear array, the matrix completion theory and Hankel matrix characteristic are exploited to transform the undersampling data matrix into a two-fold Hankel matrix. The completed data matrix is reconstructed by inexact augmented Lagrange multiplier method and the accurate angle estimation is achieved. Simulation results demonstrate that the proposed method is still effective with damaged and missing elements and show the tendency of the proposed method versus the different elements damage of the uniform linear array.关键词
