Abstract Phase synchronization is a key issue in bistatic and multistatic Synthetic Aperture Radar (SAR) imaging. This paper discusses this issue based on experiment data, presents a multi-PRF link synchronization scheme, which solves frequency measurement ambiguities by using of Chinese remainder theorem and accurately estimates random phase by duplex multi-channel link with low synchronization frequency. The performance of presented scheme is analyzed in theory and demonstrated with simulations.
