The Results of Verification of Data Obtained from TerraSAR-X Spacecraft Using Ground Test Facilities

Abstract

In this paper, the experience of interaction of different organizations within the implementation of the technique of validation of the onboard special-purpose equipment (SPE) of the space system intended for the Earth remote sensing (SS ERS) in the radar range under conditions of full-scale operation. The results of estimation of the spatial resolution and radiometric characteristics of the equipment installed onboard TerraSAR-Х spacecraft are displayed. The data were obtained using the implemented technique based on the radar survey of specially manufactured ground test objects. The possibility of the continuous operation of the verification measurement system for the validation of characteristics set for the ERS radar facilities is shown.
