Abstract

A novel vectorized method for the estimation of direction of arrival (DOA) and frequency of arrival (FOA) is presented in this paper for the uniform linear array (ULA). Firstly, a vectorized data form is employed to estimate the DOAs and FOAs at the same time. Then, based on the subspace methodology, the DOAs and FOAs can be matched quickly. By using orthogonal projection, the accuracy of the parameters is improved at last. The proposed method can estimate more signals than the sensor number of the array. Simulation results validate the effectiveness of our method.
