40.事实证明，星载差分合成孔径雷达干涉测量法是监测环境现象，特别是观测冰川和检索有关冰川表面地形和动态信息的一个有力工具。在过去十年中，这一技术的使用已成功地从空间扩展到地面观测，作为一种工具，用于在较小规模上监测单一的滑坡、不稳定的斜坡，以及最近监测被雪覆盖但尚未形成冰川的地区。这封信报告了为评价地面微波干涉测量法在估计属于冰川的不稳定区域的速度方面的潜力而开展的一项实验活动的结果。这一实验表明，即使由于缺乏观测区域的地面实况，必须仔细解释数据，也有可能远程监测被监测冰川的表面位移，最远可达3公里。
Spaceborne differential synthetic aperture radar (SAR) interferometry has been proven to be a powerful tool in monitoring environmental phenomena and, in particular, in observing glaciers and retrieving information about their surface topography and dynamics. In the last decade, the use of this technique has been successfully extended from space to ground-based observations as a tool for monitoring, on a smaller scale, single landslides, unstable slopes, and more recently, areas covered by snow but not yet glaciers. In this letter, the results of an experimental activity carried out to evaluate the potential of ground-based microwave interferometry to estimate the velocity of an unstable area belonging to a glacier is reported. This experiment demonstrated the possibility of remotely monitoring surface displacements of the monitored glacier up to a distance of about 3 km even if, due to the lack of ground truths on the observed area, the data interpretation must be carefully worked out.
