Abstract

Tropospheric scattering communication has the characteristics of large single hop span, strong obstacle surmounting ability, high reliability, good anti-nuclear explosion and anti-interception ability, which can make up for the shortcomings of limited satellite communication channel resources, the shortage of microwave communication LOS transmission and the weakness of poor fiber mobility, and will play an important role in the future information system operations. Through three aspects of research, we have realized the time synchronization technology based on the troposcatter communication channel by using the two-way time comparison principle, including the data calculation of a single microcomputer, serial communication and LCD; FPGA data reception; Kalman filtering for differential signal processing. Finally, the demonstration results are displayed on an oscilloscope, reducing the time synchronization delay to microseconds.
