Theory and Experimental Analysis of Troposcatter Time Synchronization
摘要
Abstract
The troposcatter time synchronization(time synchronization)is a new method for achieving high precision time synchronization between distributed sites through the troposcatter channel by transmitting time transfer signal.The troposcatter time synchronization theory is briefly expounded from two aspects:One Way Time Troposcatter Transfer(OWT3)and Two Way Time Troposcatter Transfer(TWT3).The TWT3 is analyzed and established in detail,and the system structure,working process and transfer error principle are discussed.On this basis,the TWT3 experiment is carried out in Guanzhong area of Shaanxi province.Through the analysis of the results,it could be seen that the experiment verified the feasibility of the troposcatter time synchronization theory.And it is concluded that the troposcatter time synchronization accuracy is within 3 ns in 60 km and 5 ns in 90 km.The relevant research has important practical significance for promoting the application of troposcatter time synchronization theory.关键词
