The problem of two-dimensional (2D) direction of arrival (DOA) estimation with non-uniform L-shaped array is discussed. The generalized ESPRIT algorithm (GESPRIT) has an advantage of being suitable to arbitrary array geometry. However, the direct applying of (GESPRIT) algorithm in non-uniform L-shaped array (called 2D-GESPRIT) needs an exhaustive 2D spectral search, which makes it unfeasible in practice...
In this work, the direction finding of coherently distributed (CD) sources using a uniform linear array (ULA) is investigated. Conventional DSPE algorithm for localization of CD sources requires an extensive two-dimensional search of nominal DOAs and angular spreads. The proposed algorithm exploits the propagator, which is a linear operator that can be easily estimated from the received data, to identify...
This paper proposes a new algorithm to estimate the nominal direction-of-arrival (DOA) and the angular spread of multiple incoherently distributed (ID) sources. With the general array manifold (GAM) model, the nominal DOAs are first separated from the original array manifold. Then, a generalized shift invariance property inside the array manifold is identified, based on which the nominal DOAs are...
In this work, a new algorithm for angular parameters estimation of incoherently distributed sources is proposed. By using the general array manifold model, the nominal DOAs can be firstly separated from the original array manifold. Then a generalized shift invariance property inside the array manifold is identified, based on which the nominal DOAs can be estimated. The angular spreads are next estimated...
