摘要
电子信息系统的综合一体化是先进平台的典型特征,天线孔径综合将众多分立的天线单元/阵列进行整合,可显著地缩减平台天线数量,改善平台的气动和隐身性能。天线孔径综合需要满足小尺寸、高性能、低耦合等诸多要求,是射频综合系统的主要难点之一。以先进飞机平台为例,介绍天线孔径综合的总体设计技术,主要包括天线孔径综合的总体思路、电磁兼容性的考虑和典型天线样机的研制。
The integration of electronic information system is a typical feature of advanced platform.The antenna aperture synthesis integrates many discrete antenna elements/arrays,which can significantly reduce the number of platform antennas and improve the aerodynamic and stealth performance of the platform.Antenna aperture synthesis needs to meet the requirements of small size,high performance,low coupling and so on,which is one of the main difficulties of RF integrated system.Taking the advanced aircraft platform as an example,this paper introduces the overall design technology of antenna aperture synthesis,including the overall idea of antenna aperture synthesis,the consideration of electromagnetic compatibility and the development of typical antenna prototype.
