In this paper, a two-dimensional (2-D) direction-of-arrival (DOA) angle estimation method for coherent wideband signals using L-shaped array is introduced. This method estimates the elevation and azimuth angles using ESPRIT technique.The incident wideband signals are assumed to be coherent and hence some decorrelation techniques are employed to decorrelate them. Then the cross-correlation matrix is found. The proposed method reconstructs the signal subspace using cross-correlation matrix and then ESPRIT algorithm is employed to estimate the azimuth and elevation angles. This approach enables the 2-D DOA estimation without the use of peak search and is robust to noise. Simulation results are presented to verify the effectiveness of the proposed algorithm.
