Equivalent Test and Verification of Interferometric Imaging Altimeter

Interferometric imaging altimeter is a kind of satellite-borne ocean remote sensing equipment which adopts interferometric system. It has the advantages of high resolution and high precision in sea surface height measurement, so as to realize the small and medium scale observation, fine observation and near shore observation of the ocean. In order to verify the effectiveness of the satellite-borne scheme, the flight experimentation can be used for equivalent verification. In terms of working conditions, there are differences in altitude and speed between airborne and satellite-borne. In this paper, the equivalence analysis and design are carried out from the aspects of working principle, prototype development and ground test verification, so as to realize the effective verification of the satellite-borne scheme.
