N2 - This paper proposes a novel algorithm for the joint estimation of DOA, range and frequency of mixed far-field and near-field sources. Based on the second order statistics of a symmetric uniform linear array, this method constructs two correlation matrices in the first step to obtain the estimates of DOA and frequency parameters. In the second step, two more correlation matrices are derived. The range and frequency values can be obtained in this step. The resultant algorithm has a low computational cost since it only requires second order statistics. Additionally, it avoids multi-dimensional spectral search. Simulation results are presented to validate the performance of the proposed algorithm.
