Abstract Super resolution estimates of target ranges, azimuth angles and Doppler frequencies for HF-Surface Wave Radar (HF-SWR) are investigated in this paper. An algorithm based on the method of Direction Of Arrival (DOA) matrix to achieve simultaneous target parameters estimates is proposed. The estimates of target ranges, azimuth angles and Doppler frequencies can be obtained from the eigenvectors and the corresponding eigenvalues of the DOA matrix respectively. This method is computationally efficient with high resolution, and with automatic combine of the estimated target parameters. Simulation results validate the effectiveness of this method.
