Airborne systems and detection methods localisation and production of images of buried objects and characterisation of the composition of the subsurface

Abstract

The invention relates to airborne systems and methods for the detection, localisation and production of images of buried objects and for the characterisation of the composition of the subsurface. The systems comprise at least one aerial module (1) with a radar unit (11) that emits and/or captures radar signals, a positioning and guidance system (13), the accuracy of which is equal to or less than 3 cm, and a ground station (2) with a flight control system (21) and a unit for processing radar signals (23) where radar signal processing algorithms (25) are applied. The invention also relates to a method for the detection, localisation and production of images of buried objects, and to a method for characterising the composition of the sub-surface. The invention is applicable in sectors where the detection of buried objects is required, for example in civil applications (detection of anti-personnel mines), inspection of tubing or in archeology.
