Abstract An error model of transmitting array mutual coupling, gain and phase error of the synthetic transmitted beam bistatic HF-Surface Wave Radar (HF-SWR) is investigated in this paper. According to the characteristics of the error model, a transmitting array calibration method is proposed. This method employs the direct signal between receiving antenna and transmitting antenna as calibration sources, and utilizes an iterative Least Square (LS) algorithm to estimate the errors of transmitting array. Simulation results validate the effectiveness of this method.
