Abstract
In this letter, we propose a new method to estimate the pitch angle, azimuth angle and range of 3D near-field sources. The signal reception model of the 3D near-field sources is established, the range parameter is eliminated by constructing a fourth-order non-Hermite cumulant matrix. We use the Lagrange multiplier method to reduce the two-dimensional angle search to a one-dimensional angle search problem, and use the Multiple Signal Classification (MUSIC) algorithm to finely estimate the azimuth and elevation angles.The fourth-order cumulant matrix enriched with the range parameter is constructed and searched for the distance. Compared with other algorithms based on higher-order cumulants, this algorithm effectively reduces the dimension of the fourth-order cumulant matrix and reduces the computational complexity. Simulation results show the effectiveness of the method.
