摘要

本文提出了一种启发式最佳拟合抛物面（BFPH）方法，专门针对受重力扭曲影响的反射天线。首先，将最佳拟合问题表述为扭曲反射体的非线性最小二乘问题（NLSP），其中根据天线中观察到的两种典型扭曲模式，推导出对当前问题至关重要的三条启发式规则（DR）。然后，采用合适的优化算法来求解 NLSP，并为初始值的定义制定了定制策略，以确保最终解决方案的有效性和可靠性。报告和讨论的一组数值结果表明，与现有的最先进方法相比，BFPH 方法性能优越。更具体地说，它提供了更高的天线增益、更小的指向误差、更强的鲁棒性以及更好的远场模式对称性。

Heuristic Best-Fitting-Paraboloid Method for Gravity-Distorted Reflector Antennas

This article presents a heuristic best-fitting-paraboloid (BFPH) method, tailored for reflector antennas subject to gravitational distortion. First, the best fitting problem is formulated a nonlinear least-squares problem (NLSP) for the distorted reflector, wherein three heuristic rules (DRs), crucial for the problem at hand, are derived based on two typical distortion modes observed in antennas. Then, a suitable optimization algorithm is employed to solve the NLSP, in which a customized strategy is developed for the definition of the initial value in order to guarantee effective and reliable final solutions. A set of numerical results are reported and discussed to demonstrate the superior performance of the BFPH method in comparison to existing state-of-the-art methods. More specifically, it supplies higher antenna gain, reduced pointing error, enhanced robustness, and better symmetry in the far-field pattern.
