Automated high-resolution ground-penetrating radar prospection with an uncrewed ground vehicle at an archaeological site
Prospection radar haute résolution sur un site archéologique en utilisant un véhicule autonome.
Résumé
Although large progress has been made in geophysical data acquisition, the survey of large areas together with a high spatial resolution remains time-consuming even when using multiple sensors in parallel. In order to overcome this problem, one possibility is the use of uncrewed aerial vehicles. Tests with drone-borne electromagnetic induction instruments and magnetometers have been conducted Air-launched ground-penetrating radar (GPR) surveys were also tested, but result in decreasing reflection amplitudes (and therefore reduced penetration depth) and lower spatial resolution . Therefore ground-based methods should also be explored. A small, four-wheeled Clearpath Robotics Husky uncrewed ground vehicle (UGV), witha maximum speed of ~1 m/s and a payload of up to 75 kg, was tested to investigate its suitability for automated GPR prospection.
