Abstract :
This paper describes mainly the design and the features of the RadioFrequency (RF) unit which is part of the development of a novel active X-band SAR system calibrator for both PAZ satellite and airborne prototypes (RBX, RIX) by INTA. The ground calibrator consists of an active transponder path and a detector path. This system will be used for absolute radiometric calibration of SAR image data and for antenna pattern evaluation, besides it provides a monitoring of the performance of the transponder itself. During the validation phase of both the PAZ and the RBX missions in 2014 this system will be demanded.
