摘要
基于运载火箭天基遥测传输的需求和箭载平台对重量、空间及能量消耗的严格限制,本文设计了一种小型轻量化、高集成、低能耗的S波段瓦式有源相控阵天线系统.该系统包括天线阵列模块、发射组件阵列模块、功分网络模块、波束控制器及电源单元模块.本文阐述了该系统的工作原理、组成架构,并根据要求设计了天线阵列、发射组件、高可靠电源单元以及波束控制器等几种关键电路.经暗室实测,本系统中所研制的天线系统样机其波束宽度、轴比、方位面俯仰面±60°波束扫描范围内的ERIP等指标达到设计要求,与目前市场上同频段功能相似的砖式相控阵天线系统相比,其体积减小45%,重量缩减25%,能耗降低15%,更贴合箭载相控阵天线从体积、重量、经济上的应用需求,同时也为相关领域的相控阵天线系统研制提供了指导.
Abstract
Based on the requirements of space-based telemetry transmission of launch vehicle and the strict limitations of weight,space,and energy consumption on the vehicle platform,this paper designs a miniaturized,lightweight,highly integrated and low-power consumption S-band tile type active phased-array antenna system.The system includes antenna array module,T-module array module,power divider network module.beam controller and power unit module.The article elaborates on the working princi-ple and integrated architecture of the system,and designs several key circuits such as antenna array,T-module,highly reliable power supply unit and beam controller,etc,according to the requirements.The developed antenna system prototype has been tested in a darkroom,and its major indexes such as beam width,axial ratio,ERIP within the beam scanning range of±60°in the azimuth and el-evation plane all meet the design requirements.Compared with brick phased array antenna systems with similar functions in the same frequency band currently on the market,its volume is reduced by 45%,weight is reduced by 25%,and the energy consumption is reduced by 15%,which is more in line with the phased array antenna from the arrow-carrying size,weight,and economic applica-tion demand.It also provides guidance for the development of phased array antenna in related fields.
