The use of drones in non-destructive inspection applications has proven feasible and effective, making this a field with very important growth potential. This leap has been possible thanks to all the advances in different fields. The accuracy, stability, and flight time of drone platforms have also significantly improved. In addition, the payload associated with these inspections has also evolved in recent years in terms of both performance and specifications. The feasibility of using Synthetic Aperture Radar (SAR) systems in different applications related to terrestrial observation has already been demonstrated. The detection of buried objects also continues to improve its performance with regard to resolution and depth.
The CX-Geodron project is developing a drone payload based on radar equipment and postprocessing techniques for geo-referenced data to complement (and sometimes replace) LiDAR laser technologies and take the next step in underground detection applications.
