| Résumé | (disponible en anglais seulement)
This paper describes the set of four RADARSAT Precision Transponders (RPTs) developed for the Canadian Space Agency for the calibration and qualification of the
spaceborne Synthetic Aperture Radar (SAR) carried on the Canadian remote sensing satellite known as RADARSAT, launched in November, 1995. The transponder system block diagram, RF diagram, and specification development are described, as well as the
overall program which gives the transponder function in the calibration program for RADARSAT. The transponders are deployed at four strategically situated sites across Canada: Fredericton, NB; Ottawa, Ont.; Prince Albert, Sask.; and Resolute, NWT.
Some details of the sites and their sensor visitation characteristics are given. Also provided are some early results showing the use and performance of the transponders using ERS-12 and RADARSAT. |
