由于地形和表面介电特性的影响，对非海洋表面高度计数据的分析变得复杂。处理背后的理念（对于英国-解释了地球观测数据中心（地球观测数据中心）在冰盖和冰架上高度计数据的使用，并说明了所用算法的功能和性能。本文详细讨论了海洋测高与陆地测高数据处理的主要区别，即波形重跟踪和斜率校正的方法。提供了它们与Seasat卫星高度计数据和模拟表面轮廓的操作结果，以表明它们与ERS-1数据的可能性能。冰盖数据产品的内容和结构进行了说明，其预期的应用进行了讨论。还考虑了数据的未来修改和校准/验证。
The analysis of altimeter data over non-ocean surfaces is complicated by the effects of topography and the dielectric properties of the surface. The philosophy behind the processing (for the U.K.-Earth Observation Data Centre) of altimeter data over ice sheets and shelves is explained and a description of the function and performance of the algorithms used is provided. The methods available for waveform retracking and slope correction, which present the primary difference between ocean and land altimeter data analysis, are discussed in detail. Results from their operation with Seasat altimeter data and a simulated surface profile are provided to indicate their likely performance with ERS-1 data. The contents and structure of the ice sheet data product is described and its intended applications discussed. Future modifications and calibration/validation of the data are also considered.
