In this paper

a joint estimation algorithm of frequency and two-dimensional (2-D) direction of arrival (DOA) is presented for L-shaped array.It constructs a parallel factor (PARAFAC) model by covariance matrices from different sub-arrays

and calculates frequency and 2-D DOA parameters using the trilinear alternating least square (TALS) algorithm.The main attractions emphasize that this method efficiently eliminates nonuniform noise

while avoids multi-dimensional searching and parameter-pairing.Simulation results of root mean square error (RMSE) show the efficacy of the new method.
