Abstract

Climate change is associated with a variety of environmental phenomena, such as the melting of glaciers, the drying out of crops and soils, and an increase in the risk of avalanches. To detect and monitor these changes, satellite-based radar imaging is widely used, as it enables the large-scale mapping of the Earth's surface independent of weather and sunlight. An emerging field of research is to use radar systems mounted on unmanned aerial vehicles (UAVs) for this purpose. UAV-borne radar systems image smaller areas, but can capture them in greater detail, more flexibly in terms of flight trajectory, and at shorter repetition intervals. This article presents the capabilities of UAV-based radar systems and the associated challenges in terms of system design and imaging techniques for detecting and monitoring the effects of climate change. Current research results are shown. In addition, we give an outlook on using a swarm of cooperative UAVs, each carrying a radar. UAV swarms will enable a higher imaging quality with respect to resolution and detectability, but at the same time come with a number of additional challenges, which will be discussed in the paper as well.
利用无人机成像雷达探测气候变化影响的研究
气候变化与各种环境现象有关,如冰川融化、作物和土壤干涸以及雪崩风险增加。为了探测和监测这些变化,基于卫星的雷达成像被广泛使用,因为它可以独立于天气和阳光对地球表面进行大规模测绘。一个新兴的研究领域是使用安装在无人驾驶飞行器上的雷达系统来实现这一目的。无人机机载雷达系统成像较小的区域,但可以更详细地捕获它们,在飞行轨迹方面更灵活,并且以更短的重复间隔。本文介绍了基于无人机的雷达系统的能力,以及在检测和监测气候变化影响的系统设计和成像技术方面的相关挑战。展示了目前的研究成果。此外,我们展望了使用一群合作无人机,每一个携带一个雷达。无人机群将在分辨率和可探测性方面实现更高的成像质量,但同时也带来了一些额外的挑战,这也将在本文中讨论。
