装备时延校准及监控技术研究CSCD

装备时延校准误差是靶场测控系统中事件记录和交会定位的重要误差因素,其精确校准是实现装备时间同步的关键技术。针对装备时延问题展开研究,提出了一种物理含义清晰、易于测量的装备时延定义,实现了离散站点装备时延校准,验证了基于改进型B码的装备时延校准监控的有效性。试验结果表明,时延校准的精度达到了十微秒量级。

Research on Calibration of Equipment Delay Time and Monitoring Technology

The calibration error of equipment delay time is an important factor for events recording and intersection positioning in range measurement and control system. The accurate calibration is an important technology to achieve equipment time synchronization. Research on the equipment delay time problem, a clear physical definition of equipment delay time is put forward, which is easy to be measured. The calibration of the equipment time delay in discrete site is realized. Based on the improved B code, the effectiveness of monitoring the calibration of equipment time delay is verified. The test results show that the delay time calibration precision and accuracy reached ten microseconds.
