本文提出了一种模高斯光束分析方法。分析方法包括基于帧的Gabor变换,GB反射,和一种新的3-D GB衍射技术,开发处理从反射器边缘的散射。这种3-D GB衍射方法通过坐标变换将Zogbi的解决方案优雅地扩展到实际场景中。该方法不仅可以分析法向二次曲面,而且可以分析赋形反射面。此外,模块化处理已被引入,使该方法能够分析多元素系统。对电大尺寸偏置反射面和三反射面紧缩场天线系统的仿真结果表明,该方法与传统光学方法具有较好的一致性。三反射面CATR系统的实测结果表明了该方法的模块化和有效性。
A modular Gaussian Beam (GB) analysis method is proposed in this letter. The analysis method consists of frame-based Gabor transformation, GB reflection, and a novel 3-D GB diffraction technique that was developed to handle the scattering from the reflector edge. This 3-D GB diffraction method gracefully extends Zogbi's solution into practical scenarios via coordinate transformation. The proposed method can analyze not only normal quadric surfaces but also shaped reflectors. Also, modular treatment has been introduced to make this method capable of analyzing multielement systems. Simulation results of an electrically large offset reflector and a tri-reflector compact antenna testing range (CATR) system show good agreement with physic optics (PO) method. The measured result of tri-reflector CATR system demonstrates the modularization and efficiency of the proposed method.
