短波战术电台同步授时及时钟保持技术研究

摘要

通过对四种同步授时技术和两种时钟保持技术的优劣分析,设计出满足战场环境下短波战术电台需求的综合性同步授时及时钟保持系统.该系统集北斗授时、GPS授时、短波授时和高稳晶振保持电路于一体,有效解决了短波通信网中各短波战术电台之间时钟不同步的问题.%A kind of comprehensive synchronous timing and clock conservation system which can meet the requirement of short-wave tactical radio under the condition of battlefietd is designed by analyzing the merits and demerits of four synchronous timing technologies and two clock conservation technologies. The Beidou timing system, GPS timing system, short-wave timing system and conservation circuit of highly-stabilized quartz crystal oscillator are integrated into the system, which effectually resolves the problem that the clock do'not synchronous among one short-wave tactical radio and the others in short-wave commumcation web.
