摘　　要：流星余迹通信系统一般应用于气象数据采集、自然灾害预警、应急保障通信等多种领域,是国家战略通信的重要组成部分。八木天线是流星余迹通信中主要天线形式之一,目前,国内外对八木天线的电气研究日臻成熟,但是同时满足宽频带、大功率、高机动性等多种需求的车载八木天线尚未见报道。本文设计了一种车载电动八木天线,既可满足宽频带、大功率的电气指标,又可满足自动展收的高机动性要求,并且对天线工作形态下的抗风强度进行了仿真分析,结果表明,天线强度满足设计要求。The Meteor Burst Communication(MBC)system is an important part of national strategic communication.It is used in many fields,such as meteorological data collection,natural disaster warning,emergency support communication.Yagi antenna is the main antenna form used in the MBC.The research on Yagi antenna has received much attention at home and abroad.However,the vehicle mounted Yagi antenna with characteristics of wideband,high power,and high mobility have not been reported.A vehicle-mounted electric Yagi antenna is designed in this paper.The proposed antenna has many advantages,such as wideband,big power,and automatic expansion and withdrawal.Besides,the wind strength of the proposed antenna is simulated and analysed.And the simulated results show that the good strength is received.
