提出了一种计算双反射面天线远场的物理光学算法。该算法也可以用于单反射面天线，是特别有用的许多反射面天线的设计问题，其中需要涉及迭代分析的优化技术。它是基于离散化的表面在一些准相等的面积和准平方补丁，取代其平面和平方等效的快速计算的基础上分析梁。一个很好的折衷之间的补丁的数量和表示的字段在任何补丁的复杂性。结果表明，该算法的准确性和效率方面的CPU时间消耗。
A novel Physical Optics algorithm to compute the far field of dual reflector antennas is presented. The algorithm can be also used with single reflector antennas and is particularly useful for many reflector antenna design problems where optimization techniques involving iterative analysis are required. It is based on the discretization of the surfaces in a number of quasi-equal area and quasi-squared patches that are substituted by their planar and square equivalents for a fast computation based on analytical beams. A good compromise is found between the number of patches and the complexity of the representation of the fields at any patch. The results demonstrate the accuracy of the algorithm and its efficiency in terms of CPU time consumption.
