天线方向图的复射线仿真

Simulation of Antenna Pattern by Complex Rays

根据复射线理论，利用复源点高斯波束场来模拟天线的远场方向图。本文提出三种模拟方法，即主瓣匹配法、峰值匹配法和逐点匹配法，给出了多种方向图的仿真结果。数值分析和优化结果表明，复射线峰值匹配法是一种精确实用的天线方向图仿真技术。

Based on complex ray theory,the Gaussian beams emitted by complex source points are employed to simulate the far-field pattern of antennas.In this paper.three methods of simulation are proposed,i.e.miainlobe matching,peak matching and point-by-point matching,and some calculation results for varieties of patterns are given.Numerical results of analysis and optimization show that the peak matching method is an accurate and practical approach for antenna pattern simulation.
