摘　　要：介绍了方向图重建方法,并将该方法应用在自适应阵列的互耦校准中。该方法基于天线方向图与阵列接收信号间的关系,通过对阵列单元方向图的变换得到阵列互耦校准矩阵。方向图重建方法对于阵列单元结构具有广泛的适应性,不仅可用于线天线阵列,也可用于由微带天线这类平面单元构成的阵列中。论文推导了互耦校准矩阵的公式,并采用一个对称振子阵列、一个微带阵列和一个柱面共形阵列验证了本方法的有效性。The element pattern reconstruction method is proposed to calibrate the mutual coupling effect of the adap- tive antenna arrays. The proposed method is based on the relationship between the element patterns and the receiving signals of the array. The mutual coupling calibration matrix is obtained via the transformation of the elements patterns of the array. The element pattern reconstruction method is characterized by the wide adaptability of the element structures. It can be used not only in the array composed of wire elements but also in that composed of planar antennas such as the microstrip antennas. The formula of the calibration matrix is developed and three antenna arrays including a dipole array, a microstrip array and a conformal array are employed to verify the effectiveness of the new method.
