无人机(UAV)技术的进步促进了其在农林、监控和安全以及基础设施检查等广泛领域的应用。无人机的优势之一是通过在其上放置不同类型的传感器来进行远程检查和传感的能力。在这个意义上，基于无人机的探地雷达(GPR)系统特别令人感兴趣，因为它们结合了无人机和GPR的优势，从而产生了能够对难以进入的场景进行快速扫描的非接触式地下传感和成像系统。本文综述了基于无人机的探地雷达系统的进展，描述了它们的体系结构和子系统。特别是，对不同的基于无人机的探地雷达系统进行了分析，重点介绍了在每种情况下采用的技术解决方案和已经实现的探测能力。还将注意为获得地下三维高分辨率图像而实施的方法。最后，将讨论这些系统面临的主要挑战，即进一步提高扫描吞吐量和检测精度。
Advances in unmanned aerial vehicle (UAV) technology have fostered its use in a wide range of areas, such as agriculture and forestry, surveillance and security, and infrastructure inspection. One of the advantages of UAVs is their ability to conduct remote inspection and sensing by placing different kinds of sensors on board them. In this sense, UAV-based ground-penetrating radar (GPR) systems are of particular interest as they bring together the advantages of UAVs and GPR, resulting in contactless subsurface sensing and imaging systems capable of performing a fast scanning of difficult-to-access scenarios. This contribution reviews the advances on UAV-based GPR systems, describing their architecture and subsystems. In particular, an analysis of different UAV-based GPR systems is presented, focusing on the technical solutions adopted in each case and the detection capabilities that have been achieved. Attention will be also given to the methodologies implemented to obtain 3D high-resolution images of the underground. Finally, the main challenges faced by these systems concerning further improvements of the scanning throughput and the detection accuracy will be discussed.
