Analysis of Influence on System Performance from InSAR Space Synchronization Based on Formation Satellites

In InSAR height measurement system based on formation satellites, time synchronization, phase synchronization and space synchronization should be established by the radars cooperated with each other in bi-static mode. The space synchronization requirement is discussed on demand of the InSAR height measurement under the condition of formation satellites. The influence of space synchronization on InSAR system performance on the height measurement accuracy and the resolution is analyzed.
