降低天线付瓣电平是天线设计的一个重要问题,对于大型相控阵天线,通常采用等间距密度抽样阵以降低天线付瓣,国外资料上介绍的设计方法叫做统计法,这个方法是借助计算机建立在大量计算的基础上,从中选择一个较好的排列。本文介绍的相关法和综合法,可以不用计算机就能迅速获得一个好的排列,这是总结了我们工作中的经验提出来的新方法,尚需在应用中不断完善,特别是相关法提出的单元密度相关设计这一问题,虽改进了统计法的设计,但其理论分析有待深入研究。
Reducing the level of the antenna to pay for the flap is an important issue in the antenna design. For large-sized phased-array antennas, an array of equally-spaced densities is usually used to reduce the antenna flap. The design method introduced in foreign materials is called the statistical method. This method uses a computer Based on a large number of calculations, choose a better arrangement. This article describes the relevant law and comprehensive law, you can quickly get a good arrangement without a computer, which is summed up the new methods of work in our experience, still need to continue to improve the application, especially the relevant law The problem of unit density related design, although improving the design of statistical method, but its theoretical analysis needs further study.
