“动中通”系统中的跟踪识别技术

天线跟踪与卫星识别是"动中通"系统中的关键技术.首先在对各种跟踪方式比较分析的基础上,提出了一种基于惯性制导、程序跟踪和圆锥扫描跟踪的组合天线跟踪方案,缩短了系统搜索卫星的时间,提高了天线跟踪卫星的精度;而后通过分析卫星可供识别的特征,提出了应用解码后的数据流特征进行识别卫星的方案,降低了系统对传感器部件的精度要求,降低了系统成本.

Research on Tracking and Identification Technique for "Communications in Moving" System

Antenna tracking and satellite identification is the key technique for"communications in moving" system.First,this paper introduced a type of antenna tracking method based on inertia guiding,program tracking and conical scan tracking by analyzing and comparing of various modes of tracking.This type of antenna tracking method shortened the satellite tracking time of the system.Secondly,a type of satellite identification method was brought forward by the characteristic of the decoding data,which was based on ...
