A new method based on fourth-order cumulant for the joint estimation of the range and DOA of spatial near-field sources is presented. The proposed method adopts the non-centro-symmetric array, and constructs three cumulant matrixes using received array data; the aperture loss is effectively avoided. The method estimates the DOA and range parameters by the tripartite relationships among subspace matrixes,...
A new two-dimensional direction of arrival (2D DOA) estimation method is proposed, in this paper. The presented method makes using of blind source separation method based on the second-order identification to estimate the array response matrix. Via the rotational invariance techniques, we can estimate the 2D DOA from the array response matrix estimation. The estimated elevation angles and azimuth...
This paper describes how variations in elevation angle of incoming signals can affect the accuracy of Adcock direction finders (ADFs) in estimating the azimuth direction of arrival (DOA). In accordance with Adve and Sarkar [2000], Maxwellpsilas equations are solved to calculate the mutual coupling characterizing a typical ADF. The voltages at the antenna elements are calculated under several plane-wave...
