Abstract

In the past two decades, the object characteristics at L- and C-band backscattering coefficient have been widely studied, but little attention was paid to S-band, due to the main spaceborne SAR sensors are designed at L- and C-band by now. HJ-1C is planned to be launched at the end of 2009, on which an S-Band SAR is loaded. For the applications of S-band SAR, it is necessary to obtain backscattering coefficient and analysis object characteristics at this band. In this paper, S-band relation models are preliminarily analysed for several typical ground objects, using measurements obtained by the scatterometer system of University of Electronic Science and Technology of China (UESTC). Result shows the S-band scatterometer system is instable in some cases, but object characteristics can be revealed qualitative. Therefore, some improvements shall be done to advance scatterometer's performance and field-work methods when more measurements were taken. For the quantitative analysis of S-band measurements, observations from SMEX02 PALS instrument are used to compare with the theorical simulation from water-cloud model, the result shows good.
