Abstract
In the field of composite guidance, this paper analyzes three time synchronization methods for multi-source data fusion, establishes the standard measurement principle based on synchronization error, and compares the time synchronization effect and the measurement noise propagation result of the above three methods in terms of time slice and target maneuver. Simulation results indicate that the piece-wise linear interpolation method is the easiest method, has better inhibition effect on the uncertainty of noise propagation during time synchronization, is insensitive to time slice and target maneuver, and meets the requirements of multi-source composite guidance on time synchronization of data fusion.
