摘要
"动中通"移动卫星通信终端可广泛应用于高数据率卫星通信、新闻采集、公安值勤、抢险救灾、打击恐怖主义、海上缉私等领域,尤其适用于各种军事通信。介绍了"动中通"移动卫星通信终端伪单脉冲自跟踪天线系统的组成,合成信号C/N0的计算,以及在运动载体姿态快速变化条件下提高天线跟踪精度和因遮挡导致的跟踪失效后快速重捕目标的关键技术。
Terminals in vehicle mobile satellite communications can be widely used in high date satellite communications system, news collection, policemen patrolling the streets, dealing with emergency, striking terrorism and smuggle. This system is special suitable for military communications. There is a mono pulse auto tracking antenna in the system. Calculation of combination C/N0 ,antenna tracking precision and quickly re- acquiring objects technology are presented.
