Abstract :
During the first SIR-C/X-SAR mission (SRL-1), the Chinese airborne SAR (CASSAR) campaign was performed in the Beijing test site simultaneously when SRL-1 overflew through the test site. Meanwhile, the backscattering measurement was carried out on the ground using the truck-mounted scatterometer, and ground-truth data were collected in real time, such as soil moisture, surface roughness, biomass. The backscattering data acquired in the platforms with different altitudes could be used for calibration and better understanding of interaction mechanisms of electromagnetic radiation with natural surfaces. In this paper, the calibration results and ground truth data analysis of this-campaign are put forward
