基于WINCE5.0的CINRAD雷达GPS校时系统的设计与实现

Design and implementation for CINRAD GPS timing system based on WINCE5.0

时间同步是新一代天气雷达(CINRAD)系统普遍存在的问题。针对新一代天气雷达网的布局现状,采用卫星时钟作为CINRAD雷达网的时间同步校时基准时间,利用成熟的GPS校时接收模块,设计以ARM9为核心的开放式、可视化的校时主机,研制了一套智能化的新型CINRAD雷达GPS校时系统。该系统主要包括校时服务器硬件和软件,是一套校时精度高、稳定性能好、功能齐全、可全自动工作的时间同步校时系统。文中详细介绍了新一代天气雷达GPS校时系统的设计思路和工作模式。通过在不同型号雷达系统中的应用,取得了预期的效果,较好地解决了CINRAD同步自动校时的关键技术,具有重要的应用价值和潜在的经济效益。

Time synchronization is a common problem existing in CINRAD system.Based on distribution status of CINRAD network,adopting satellite clock as synchronous timing reference for CINRAD network and using mature GPS timing receiver module,the author designs an open and visual timing host computer with ARM9 as kernel and develops an intelligent new CINRAD GPS timing system.This system includes timer hardware,server and client software that is a set of synchronous timing system with features of accurate,stable,functional and automatic.This paper introduces design scheme and working mode for CINRAD GPS timing system in detail.Through experiments in radar systems of different types,it achieves desired results and solves key technologies of CINRAD synchronous timing successfully,which has important application value and potential economic benefits.
