| Summary: | The CryoSat synthetic interferometric altimeter (SIRAL) has been designed to extend the coverage of conventional pulse-limited altimeters to allow the measurement of sea ice thickness and the elevation of the marginal regions of ice sheets. The science data acquired by the instrument is of a more complex nature than the conventional radar altimeter and is in one of three forms each of which are described in the paper.Examination of simulated echoes from each of these 3 modes provides a useful insight into how the CryoSat mission will tackle its primary objectives, and how an improvement in elevation measurement will be made over its conventional satellite borne counterpart. |
