摘　　要：时间和频率同步是雷达标校系统的关键技术之一,同步的实现是系统采用两地雷达目标模拟技术所必须的;研究了一种基于GPS卫星的时间和频率同步方案,即接收GPS转发的标准时间和频率信号,采用同步模块实现标校系统舰上和岸上两地的时间和频率同步,该方案优于传统同步装置的长时间校正频率误差,提高了标校系统的时间和频率同步精度,从而减小了标校系统对雷达进行标定校准的误差。Time and frequency synchronization is a key technology of the radar calibration system,the realization of synchronization is necessary for this calibration to adopt the technology of two-point radar target simulating;A method based on GPS satellite is researched in this paper,that is realized by receiving standard time and frequency signal transmitted from GPS satellite and adopting synchronization system＇s function module to realize the time and frequency synchronization between sea-going part and harbour part,this method is superior to traditional synchronization device in aspect of long-time correcting frequency＇s error,besides it greatly enhances synchronization accuracy of time and frequency in the calibration system,so the error is reduced when the calibration system calibrates a ship radar.
