Abstract Phase synchronization of radar carrier is prerequisite to distributed satellite SAR system. In this paper, a modified phase synchronization means of distributed satellite SAR is proposed, that is, phase synchronization pulses are exchanged between satellites based on the GPS-disciplined crystal oscillators. The factors affecting phase synchronization performance are analyzed, and the performance of phase synchronization link is verified by ground test.
