基于卫星导航的时间位置标定仪器研究

Research on Time and Position Calibration Instrument Based on Satellite Navigation

气象雷达各个分系统工作运行需要一个精准的时间戳标定,以便软件后台处理数据,并且雷达系统每次运行时都要对天线反射体进行方位、仰角的标定。本文结合实际的应用场景,在传统NTP网络时间服务器的功能基础上增加了位置信息的测量,设计了一种可以同时对方位、仰角、时间进行标定的仪器,该标定仪器可以提高气象雷达观测数据的实时性和可靠性。

Radar run each subsystem work requires a precise time stamp for calibration,In order to software processing data;and radar system run will be calibration the azimuth and angle of the antenna reflector. In this paper,on the basis of the function of the traditional NTP network time server to increase the measurement location information,combined with the actual application scenario design a calibration of the instrument for the azimuth,angle,time. The calibration instrument can improve the real-time performance and reliability of weather radar data.
