Research Progress of Calibration Site and Calibration Method of Satellite Altimeter

The paper briefly introduces absolute calibration methods of sea surface height and backscatter of satellite altimeter. Also, the paper introduces two methods of absolute backscatter calibration by transponder and microwave radiometer. We also present some suggestions on choosing the calibration site based on the satellite altimeter’s characteristics, and introduce some successful calibration sites and their calibration results. The objective of this paper is to present the information on our satellite altimeter in the near future.
