An estimation algorithm for three-dimensional frequency, DOA and range of near-field sources was proposed, which used second-order statistics (SOS) matrix to estimate frequency and DOA of each source. Then the range estimation was performed with the estimated DOA through finite one-dimensional searching. This algorithm improves the precision of range estimation compared to the SOS method. Finally, the effectiveness of the proposed algorithm was verified by computer simulation.
