摘要
为降低阵列天线单元间的互耦影响,给出了一种基于矩量法的迭代综合方法,通过不断对无线阵列单元电流进行修正而求得单元激励电压,从而得到满足工程实践要求的零点。综合示例和软件仿真的结果吻合较好,证明了该综合方法的正确性和有效性。
The Coupling between array elements can make the side -lobe higher, the angles of nulls float and most classical synthesis methods inoperative because of its effects on the current of elements. So the amplitudes and phases of the elements current must be adapted to those generating perfect patterns when synthesizing with coupling. Aiming at the element stimulate voltage, mending the current coefficient, and solving by the method of Moments, the nulls meeting certain depth requirement can be obtained. The required step and time are few in this method, and the results of the examples of several types arrays agree well with the corresponding emulation results simulated by Super NEC, which prove that the method is valid and accurate.
