The EnviSat RA-2 Instrument Design and Tracking Performance

  title={The EnviSat RA-2 Instrument Design and Tracking Performance},
  author={M{\`o}nica Roca and Seymour W. Laxon and Carlo Zelli},
  journal={IEEE Transactions on Geoscience and Remote Sensing},
The EnviSat satellite embarks an innovative radar altimeter, the RA-2 which represents a new generation of radar altimeters compared to previous instruments such as the European Remote Sensing Satellite (ERS) altimeters and The Ocean Topography Experiment/Poseidon. This is due to its integration of many new features. In particular, the RA-2 is the first satellite altimeter to incorporate autonomous resolution selection and a model-free tracker. The behavior of the instrument in orbit is… CONTINUE READING
