摘要

摘要近距离传感器用于观测短时间内运行的冰川过程（如冰山崩解、冰川湖爆发洪水、昼夜表面融化）。然而，在恶劣的天气条件下，光学仪器会出现故障，而17 GHz以下的雷达系统的操作没有足够的角度分辨率来详细绘制冰川表面。这封信回顾了94 GHz毫米波雷达在大多数天气条件下获得冰川高分辨率三维测量的潜力。我们讨论了94 GHz雷达用于冰川学研究的理论，展示了其绘制冰川崩解锋图的潜力，并总结了未来的研究重点。

Glacier monitoring using real-aperture 94 GHz radar

Abstract Close-range sensors are employed to observe glaciological processes that operate over short timescales (e.g. iceberg calving, glacial lake outburst floods, diurnal surface melting). However, under poor weather conditions optical instruments fail while the operation of radar systems below 17 GHz do not have sufficient angular resolution to map glacier surfaces in detail. This letter reviews the potential of millimetre-wave radar at 94 GHz to obtain high-resolution 3-D measurements of glaciers under most weather conditions. We discuss the theory of 94 GHz radar for glaciology studies, demonstrate its potential to map a glacier calving front and summarise future research priorities.

期刊介绍： Annals of Glaciology publishes original scientific articles and letters in selected aspects of glaciology-the study of ice. Each issue of the Annals is thematic, focussing on a specific subject. The Council of the International Glaciological Society welcomes proposals for thematic issues from the glaciological community. Once a theme is approved, the Council appoints an Associate Chief Editor and a team of Scientific Editors to handle the submission, peer review and publication of papers.
