The space equalization method (SEM) is put forward in this paper to eliminate the amplitude and phase errors among antennas caused by mechanical manufacturing errors and array edge effects. After array mutual coupling calibration (MCC), an adaptive nulling algorithm based on SEM is derived, which greatly improves jammer cancellation performances. The experimental results demonstrate the advantage of SEM.
