This award is for support of a Small Grant for Exploratory Research (SGER) to examine the feasibility of applying conventional and interferometric synthetic aperture radar techniques to map the basal portion of glaciers. Conventional imaging synthetic aperture radars (SARs) provide only a two- dimensional view of the bottom of the ice, and limited information on basal physical properties. Three dimensional maps of the bottom can be obtained with Interferometric Synthetic Aperture Radar and would significantly enhance the utility of radar data in the study of glacial dynamics. This feasibility study will examine the characteristics of electromagnetic propagation through glacial ice, the optimum conditions for synthetic aperture radar imaging and the scattering characteristics of the bottom ice. The result of this work will be a determination of the optimum set of system parameters needed for a synthetic aperture radar to map the basal characteristics of glacial ice.

该奖项是为了支持探索性研究（SGER）的小额赠款，以研究应用常规和干涉合成孔径雷达技术绘制冰川基础部分的可行性。传统的成像合成孔径雷达（sar）只能提供冰底的二维视图，并且关于基本物理性质的信息有限。利用干涉合成孔径雷达可以获得冰川底部的三维地图，这将大大提高雷达数据在冰川动力学研究中的实用性。本可行性研究将探讨电磁在冰川冰中的传播特性、合成孔径雷达成像的最佳条件和底部冰的散射特性。这项工作的结果将是确定合成孔径雷达绘制冰川基本特征所需的最佳系统参数集。
