摘　　要：提出空间均衡方法用来消除由天线的机械加工误差和阵面的边缘绕射引起阵元间的幅相误差 .对阵列互耦校正后 ,推导了一种基于空间均衡方法的自适应零点形成算法 .该方法极大地提高了阵列的干扰对消性能 .实验结果证明了空间均衡方法的优越性 .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.
