Abstract The cluster micro-satellite Synthetic Aperture Radar(SAR) system is an inno-vative SAR system brought forward recently. In the cluster micro-satellite system, tech-nology of cross-track interferometic SAR imaging processing is studied. The influence of the rotating of the cluster micro-satellite on the baseline and the interferometric phase is analyzed. The corrected formula of the baseline and the interferometric phase are derived. By computer simulation, the errors between corrected and uncorrected height measurement are compared. The analysis results verify the correction of the formula and the necessity to correct the baseline and the phase.

Key words： Cluster micro-satellite system Synthetic Aperture Radar（SAR） Iuterfero-mctric phase Available baseline Height error
