Decoupled Estimation of 2D DOA for Coherently Distributed Sources Using 3D Matrix Pencil Method

Decoupled 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...
