摘要

基于在复空间内将馈源辐射场分解为多个复馈源波束(CSB),提出了应用复源波束快速计算反射面天线辐射场的方法。每个CSB在反射面上的复反射点和复散射点可由复空间内的几何光学理论与几何绕射理论计算得到。计算机仿真结果表明,与物理光学法(PO)相比较,该方法具有计算速度快,精度较高,且计算速度与频率无关的优点。

Abstract

Based on spreading the source into a set of complex source beams (CSBs) in complex space, the method of using complex source beams to calculate radiate field is put forward. Then the complex points of surface reflection and edge diffraction on the complex extension of the reflector are computed via GO and GTD methods. It's validated by computer simulation that CSB method, compared with PO method, has a lower time computation with the same accuracy and the rate computation of CSB method has nothing to do with the work frequency.

Key words： complex source beam (CSB); geometrical optics theory (GO); geometrical diffract theory; physical optics method (PO)
