Abstract

The problem of two dimensional direction of arrival estimation of coherent signals using three parallel uniform linear arrays is investigated. In the proposed method a pre-processing technique, forward and backward spatial smoothing is employed to resolve the coherency. Then the propagator method is exploited for estimating the two dimensional angles with automatic pairing for three parallel uniform linear arrays. Numerical simulations are done to show the efficacy of the proposed method. It validates the estimation accuracy, resolution and robustness of the proposed method.
