本文主要叙述了赋形反射面设计中一个重要环节——中截线设计。叙述了中截线设计的数学模型、求解方法、参数选择以及计算机程序。设计时可将所要求的俯仰方向图(平方余割方向路)代入,由计算机对 HK 参数进行选择,求解出一条符合要求的中截线,并对该中截线进行俯仰方向图测定,整个过程在几分钟之内即可完成。面天线设计与研制计算机化既便于优化设计,又可避免人力、物力的浪费.该程序经工程实践验证,是切实可行和有效的。
This paper mainly describes the design of the reflective surface of an important part - the design of the mid-line. Describes the mathematical model of midline design, solution method, parameter selection and computer program. The design can be required when the pitch direction (squared residual direction road) into the computer by the HK parameters to choose, to find a meet the requirements of the intercept, and the intercept of the pitch pattern determination, the whole The process can be completed in a few minutes. Surface antenna design and development of computerized not only facilitate the optimization of design, but also to avoid the waste of manpower and material resources.This program verified by engineering practice is feasible and effective.
