A Novel Simple DOA Estimation Algorithm Based on Direct Data Domain Approach Using Phase-only Conjugate Gradient Method

摘要：

Recently, a direct data domain least square (D3LS) approach has been developed so quickly for array signal processing in mobile communication and radar application. With D3LS approach, only a single data snapshot is required, instead of multiple snapshots needed to form a covariance matrix in conventional algorithms. Moreover, The phase-only algorithms are so attractive due to the advantage on simple hardware implementation. Therefore, this paper proposes a novel simple direction of arrival (DOA) estimation algorithm based on D3LS approach using phase-only conjugate gradient (CG) method. Simulation results show that the proposed algorithm can estimate the DOAs of signals accurately and deal well with coherent signals.
