摘要
针对双反射面天线波束赋形优化过程中,物理光学法(PO)在计算副反射面对主反射面作用耗时较多的问题,提出了一种物理光学法的加速方法,减小计算复杂度加快求解,并给出了详细的计算公式。对Ka波段卡塞格伦天线进行远场分析,文中方法与物理光学法计算结果相吻合,计算效率得到显著改善,该方法的有效性得到验证。
In order to solve the time-consuming problem of shaped reflector antenna optimization and design, the method of aggregating the configuration is adopted to reduce the computational complexity and speed up the solution. The integral equation is converted into the form of numerical summation. The far field patterns of Cassegrain antenna in Ka-band are analyzed. The result agrees well with physical optics. The computational efficiency is proved and the validity of the proposed approach is verified.
