Thus far in the book we have concentrated primarily on the analysis and design of
antennas. In the analysis problem an antenna model is chosen, and it is analyzed
for its radiation characteristics (pattern, directivity, impedance, beamwidth, effi

本文给出了一种利用幅相加权对阵列天线进行全局优化的方法。为了使天线的辐射波束形成给定的
方向图，采用联合应用DFP和BFGS公式的变度量算法对阵列天线各单元的馈电幅度和相位分布进行优化，
通过C++语言编程计算实现，从而使得优化后的阵列天线主波束形状能够与预给波束形状相吻合，达到设计
要求。全局优化是本文的特色，它弥补了局部优化结果的精确度依赖于初始值的缺点，因而得以保证通过优
化得到的天线主波束与给定波束的主瓣相吻合，副瓣也得到有效控制。该方法具有快速收敛，计算量小等优
