High Precision Dynamic Prediction and Time Synchronization Based on High Speed Motion Platforms

Abstract

With the increasing of information technology, there are Doppler frequency shift and clock errors between master station and slave station in Multi-Warhead Collaborative Multi-Base Radar System (MCMRS), thus precise time synchronization is needed. Therefore, this paper presents a new time synchronization method, which integrates PN code ranging and dynamic phase shift module based on digital clock management (DCM) in FPGA to measure the clock error precisely. At the same time, we use Extended Kalman Filtering technique to smooth the measuring results. This method can not only accurately compensate for the generated synchronization pulse offset, but also be easy to implement on hardware. This algorithm can be widely used in the military field without GPS.
