Error Analysis and Calibration of Two-way Microwave Time Transfer Equipment
Through Analyzing the advantages and disadvantages of two-way satellite time transfer (TWSTT), two-way time microwave transfer and two-way optical fiber time transfer, selects two-way microwave time transfer method as time synchronization method of line-of-sight range.It introduces the basic principle of two-way microwave time transfer, using mathematical formula deduces error sources.The influence of ground equipment on the synchronous precision are analyzed in detail, and describes the way that reduces the modem delay and the calibration.After analyzing the synchronous precision of two-way microwave time, it can reach ns magnitude, and this method is satisfied to the requirements of multi-radar and ships in the time synchronization precision.
