Sparsity-Based Underdetermined DOA Estimator via Toeplitz Matrix Reconstruction for Sparse Array
2021 IEEE 4th International Conference on Electronics Technology (ICET)(2021)
摘要
In this paper, we provide a novel idea to achieve underdetermined direction of arrival (DOA) estimation for sparse array by introducing covariance matrix reconstruction into sparsity-based algorithms. Based on the Toeplitz property of covariance matrix of uniform linear array, the covariance vector sparsely representation (CVSR) model is established and DOAs can be retrieved through sparse reconst...
