| Abstract | 本发明涉及一种赋形双反射面天线最佳吻合赋形面参数的计算方法，该方法将赋形双反射面天线的馈源‑副面‑主面匹配系统拆分成馈源‑副面‑“焦线”和主面‑“焦线”两个系统，它们通过“焦线”匹配实现与原赋形双反射面匹配系统的等效，使得对于仅讨论主面实际形面误差的问题简化为在主面‑“焦线”系统内讨论，既简化了分析过程，几何意义极易理解；又使得问题研究的对象更有针对性。该方法将赋形反射面最佳吻合赋形面的参数以简单清晰的思路求解出来，可通过最佳吻合参数计算出实际赋形反射面的基准面，为大型赋形双反射面天线的面型精度描述、结构保型设计、副面位姿调整和主动面调整提供了参考基准，具有较高的实际应用价值。 |
| Other Abstract | The present invention relates to a calculation method for a parameter of an optimally-fit shaped surface of a shaped dual-reflector antenna. According to the method, a feed- subreflector- main reflector matching system of a shaped dual-reflector antenna is split into a feed- subreflector- "focal line" system and a main reflector- "focal line" system, and the two systems achieves equivalence to the original shaped dual-reflector matching system, so as to simplify a pure discussion of a main reflector actual shaped surface error problem into a discussion in the main reflector- "focal line" system, so that not only an analysis process is simplified and a geometric meaning is easy to understand; but also an object of problem researching is more targeted. According to the method, a parameter of an optimally-fit shaped surface of a shaped reflector is solved with a simple and clear idea, and a reference surface of an actual shaped reflector can be calculated by means of an optimally-fit parameter, and therefore, the method provides a reference for surface type precision description, structure shape-maintaining design, subreflector posture adjustment and active surface adjustment of large-scale shaped dual-reflector antennas, and has relatively high actual application value. |
