A method based on fourth-order cumulant was presented to estimate the range, elevation, azimuth, and polarization parameters of near-field sources. The method adopted non-centra-symmetric cross array, and every sensor consisted of the orthogonal dipole-pairs with the same coordinate axis direction, which measured the x-axis and y-axis electric-field components of the near-field signals. The method...
A new method based on fourth-order cumulant for the joint estimation of the range, elevation and azimuth of spatial near-field sources is presented. The proposed method adopts non-centro-symmetric cross array, constructs cumulant matrixes using received array data, and constructs five signal subspace matrixes through SVD decomposition. According to the tripartite relationships among subspace matrixes,...
