- A parameter estimation algorithm of direction of arrival (DOA), based on a nonuniform L-shaped array, is presented for plane-wave signals. According to relation of the two x-axis and y-axis subarrays, a set of rough but unambiguous direction cosines estimates in x and y direction are obtained. By disambiguating the phase ambiguities another set of precise and unambiguous direction cosines estimates in x and y direction are obtained. Without spectral peak searching, this method has advantages of the small amount of calculation and high precision. Simulation results verify the effectiveness of the algorithm.
