摘要

提出了一种综合天线阵列所有电磁特性(包括相互耦合)的最佳波束形成方法。最优波束形成技术使天线阵的总辐射功率最小,同时保持了期望方向上的响应。通过考虑有源单元方向图和阻抗矩阵,得到了一种计算效率高的波束形成算法。仿真结果表明,该算法适用于有平台存在的天线阵列

Optimal beam forming in the presence of mutual coupling
An optimal beam forming method is proposed which incorporates all electromagnetic characteristics of the antenna array, including mutual coupling. The optimal beam forming technique minimizes the total power radiated by the antenna array while the response in a desired direction is maintained. By considering the active element patterns and the impedance matrix a computational efficient beam forming algorithm is obtained which is able to manage all mutual coupling effects. Simulation results show the performance of the proposed algorithm applied to an antenna array in the presence of a platform
