Rotating fan-beam scatterometer (RFSCAT) is a new kind of spaceborne scatterometer for
ocean surface vector wind (OSVW) measurement. In this paper, some consideration about
the calibration of a Ku-band RFSCAT is presented. Both internal calibration and external
calibration are described. Preliminary analyses about the internal calibration precision and
external calibration accuracy are presented. Based on the method of Long, et al, external
calibration method for RFSCAT is proposed. Some simulation results for the external …
