The Influence of the Rotating of the Cluster Micro-Satellite on Height Measurement of InSAR
分布式卫星的环绕对InSAR测高精度的影响

The cluster micro-satellite Synthetic Aperture Radar(SAR) system is an innovative SAR system brought forward recently. In the cluster micro-satellite system, technology of cross-track intcrferometic 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 uucorrccted height measurement are compared. The analysis results verify the correction of the formula and the necessity to correct the baseline and the phase.
