Abstract

The SIR-C/X-SAR SRL-3 topographic mapping mission was conceived by JPL to provide a global topographic mapping of the planet Earth and to acquire multi-frequency/multi- polarization SAR data over selected sites. The major benefits expected by this eleven-day shuttle mission, now officially called Shuttle Radar Topographic Mapper (SRTM), are to support many branches of the earth sciences providing an accurate knowledge of the surface elevation. To generate required data, SRTM will use a single-pass fixed baseline interferometer SAR system composed by the Shuttle Imaging Radar C and by the X-band SAR successfully flown twice in 1994, enhanced by two additional C-band and X-band receive- only antennae/receivers mounted on the tip of a 60 meters long retractable mast. The aspects related to the mission objectives and to design concepts of the interferometric channel of the X-SAR radar are dealt with in this paper. In particular the system configuration, the secondary azimuth beam steerable antenna, the front-end electronics and the on-orbit antennae misalignment's compensation are introduced. Finally the achievable performances are presented.
