Low-complexity estimation of 2D DOA for coherently distributed sources
We consider the estimation of two-dimensional (azimuth and elevation) direction-of-arrival (DOA) using a pair of uniform circular arrays under a coherently distributed source model. Since the coherently distributed source is characterized by four parameters, the nominal azimuth DOA, angular extension of the azimuth DOA, nominal elevation DOA, and angular extension of the elevation DOA, the comp...
متن کاملDecoupled Estimation of 2D DOA for Coherently Distributed Sources Using 3D Matrix Pencil Method
A new 2D DOA estimation method for coherently distributed (CD) source is proposed. CD sources model is constructed by using Taylor approximation to the generalized steering vector (GSV), whereas the angular and angular spread are separated from signal pattern. The angular information is in the phase part of the GSV, and the angular spread information is in the module part of the GSV, thus enabl...
متن کاملA New Method for the 2D DOA Estimation of Coherently Distributed Sources
The purpose of this paper is to develop a new technique for estimating the two-dimensional (2D) direction-of-arrivals (DOAs) of coherently distributed (CD) sources, which can estimate effectively the central azimuth and central elevation of CD sources at the cost of less computational cost. Using the special L-shape array, a new approach for parametric estimation of CD sources is proposed. The ...
متن کاملNew 2D-DOA and Angular Spread Estimation method for Coherently Distributed Sources
In many two-dimensional Direction of Arrival estimation approaches for Coherently distributed source, the computational complexity induced by high-dimensional peakfinding searching is normally highly demanding. We propose a low-complexity estimation algorithm by using the approximation to the steering to vector for small angular extensions, which estimates the nominal DOA using the phase inform...
متن کاملTwo-Dimensional DOA Estimation for Coherently Distributed Sources with Symmetric Properties in Crossed Arrays
In this paper, a novel algorithm is proposed for the two-dimensional (2D) central direction-of-arrival (DOA) estimation of coherently distributed (CD) sources. Specifically, we focus on a centro-symmetric crossed array consisting of two uniform linear arrays (ULAs). Unlike the conventional low-complexity methods using the one-order Taylor series approximation to obtain the approximate rotationa...
