A method of adaptive operating frequency selection for Over-The-Horizon Radar (OTHR), which can effectively improve the usage of spectrum resource in HF-band, is presented in this paper. A subarray with wide-band receiver is used to receive interference signals, and then the adaptive beamforming algorithm is applied to the signals separated by a few kilohertz. The frequency at which the array has the minimum output power is selected as the optimal operating frequency. Simulation results show that the method can effectively provide the optimal operating frequency for OTHR.
