The Radar Altimeter-2 (RA-2) on the European Space Agency (ESA) ENVISAT-1 spacecraft is an adaptive pulse limited radar altimeter operating at a frequency of 13.8 GHz (K-band) and at 3.2 GHz (S-band). The main objectives of the RA-2 are high-precision measurements of significant wave height and sea level determination, ocean circulation, ice sheet topography and land mapping. The 3.2 GHz channel is used to measure and correct for ionospheric delays. The RA-2 uses an adaptive range window with a bandwidth of 330 MHz for measurements over ice surfaces. The RA-2 ensures continuity with the ERS-1 and ERS-2 radar altimeters (RA).
