Abstract An algorithm of HF ground wave radar array calibration for amplitude and phase errors based on sea-echo is proposed in this paper. According to the relation between the adjacent antenna sea-echo responses for the same ocean cell, the equations of amplitude and phase errors are developed and solved. The bias of calibration results is analyzed by numerical simulation, and its application in HF ground wave radar OSMAR2000 shows this algorithm effective and credible.
