Over-the-horizon time and frequency synchronization for maneuverable radar system based on troposcatter

Time and frequency synchronization is prerequisite of coordinating multi-static radar system. However, available synchronization methods do not provide practical beyond line-of-sight synchronization especially under the condition of maneuver. Therefore, a novel time and frequency synchronization mechanism based on troposcatter has been proposed. And the main motivations of this paper are to analyze and calculate the main time delay errors, including equipment delay errors and path time delay errors, in the process of time signal transmission and calibration. The result indicates that, the time delay errors of the proposed synchronization method fulfill the requirement of beyond line-of-sight time and frequency synchronization for maneuverable radar system.
