ABSTRACT We propose a new approach to solve the problem of optimal power synthesis of array antennas, so that maximum possible bandwidth can be granted to fixed sidelobe-level performances. The proposed approach can be applied to any kind of fixed-geometry array that radiates pencil beams and to linear equispaced arrays that generate shaped patterns. The designing problem is cast as a sequence of Convex Programming optimizations. Numerous numerical experiments, including full-wave synthesis of realistic antennas, were carried out and their results discussed here to assess the array antennas’ capability of achieving ultra-wideband performances.

基于凸规划的固定几何阵列带宽最大化

摘要 我们提出了一种解决阵列天线最佳功率合成问题的新方法，以便可以为固定旁瓣级性能提供最大可能的带宽。所提出的方法可以应用于任何类型的辐射笔形光束的固定几何阵列和生成成形图案的线性等距阵列。设计问题被转换为一系列凸规划优化。进行了大量数值实验，包括真实天线的全波合成，并在此讨论了它们的结果，以评估阵列天线实现超宽带性能的能力。
