The study of the parameters to interferometric SAR height-measurement and velocity-measurement precision in the Cluster Micro-Satellite system

The Cluster Micro-Satellite synthetic aperture radar system is an innovative SAR system brought forward recently. CT-InSAR and AT-InSAR is the principal working models in this system. This paper researches chiefly the influence of the difference of all kinds of parameters in the system to the height precision of CT-InSAR and analyzes the measurement precision requirement of all sorts of data in the swath. And we analyze the requirement of the velocity measurement precision to the baseline precision. The simulation result enunciates that the requirement of baseline precision of CT-InSAR is much more precise than that of AT-InSAR.
