Direction of Arrival and Range Estimation for Near Field Sources based on the Cumulant Matrix

Year: 2024

Type: conference-paper

Abstract: This article proposes a near-field source arrival angle and distance estimation method based on cumulative moment matrix. Firstly, construct a joint cumulative moment matrix, and then perform eigenvalue decomposition. By using the rotational invariance of the signal subspace to estimate the angles of the near-field source and the orthogonality between the noise subspace and the source direction vector to estimate the distance, the simulation results show a significant improvement in estimation accuracy and resolution.
