Research on the Method of Double Curvature Deformation of Parabolic Antenna Three-dimensional Modeling

针对设计过程中,对于双曲率变形抛物面天线,难以使用常规建模方法准确表达的问题,通过分析某型天线的几何特性,提出一种可行的建模方法.最后应用此法在Pro/E中实现了该型天线反射面的三维建模,验证了其可行性.

Accurately modeling is very difficult to use conventional methods for the design process of double curvature deformation of parabolic anten-ha. Analysis of the geometry of the antenna characteristics,and put forward a viable method of modeling. Finally, application of the method in the Pro/ E in a certain type of reflector antenna to achieve the threedimensional modeling, to verify its feasibility. Key words,
