A 3-D Parameter Joint Estimation Algorithm of Near Field Sources Based on MP Algorithm

摘要

A method based on fourth-order cumulant and MP algorithm for the joint estimation of the range, elevation and azimuth of near-field sources is presented. The method adopts non-centro-symmetric cross array, the aperture loss is effectively avoided. In addition, parameter pairing information is contained in the magnitude value of the generalized eigenvalue, so there is not require the extra program to pair parameter of various parameters. The performance of the method is verified by computer simulations.
