Abstract

Ground-Penetrating Radar (GPR) takes advantage of the ability to penetrate invisible materials to detect and build images of buried or hidden objects underground and has been widely used as a remote sensing tool. However, ground-penetrating radar is difficult to deploy for complex terrain in traditional ways, such as mounted on carts. With the development of Unmanned Aerial Vehicles (UAV) platforms, UAV-based GPR systems help expand the working capabilities and increase the efficiency of GPRs. This paper first provides a general overview of the current UAV-based GPR systems and some challenges. Next, based on the overview results, a fabricated UAV-based GPR system is presented in detail. The test results prove the system's correctness and feasibility. Finally, we summarize the results and prospects of this promising technology
