摘要 分析阵列馈源激励的抛物面天线方向图综合问题。通过调整馈源阵列的激励分布实现抛物面天线的波束扫描。通过物理光学法计算出单馈源抛物面天线的方向图,在此基础上求解最小二乘问题来优化阵列的激励系数,有效综合了抛物面天线的方向图,达到控制主瓣扫描方向、旁瓣电平、交叉极化分量等设计要求。给出算例,验证了本文方法的有效性。 In order to use parabolic antenna to generate scanning beams,excitations of the feeding array are adjusted.Single-feed parabolic antenna patterns are calculated using PO,and based on this,the excitation coefficients of the array are optimized by solving the least-squares problem and the antenna pattern is synthesized efficiently to control the side-lobe level and cross-polarized components,and to scan the beam direction.Numerical simulation results are given to verify the feasibility of this method.
