3D MIMO GPR
Ground-penetrating radar for real-time detection and 3D image reconstruction of subsurface structures
What it can do
This 3D radar technology is specifically designed for civil engineering applications, offering detailed three-dimensional imaging of underground utilities such as pipes, cables, and other buried infrastructures. The high-resolution images are accurately geolocated with centimeter-level precision and are being integrated into underground digital twin models. In addition to utility mapping, the radar provides real-time soil permittivity without calibration. Broader applications could include the detection of underground cavities and mines.

Working with CEA-Leti
Global transportation infrastructure construction and maintenance leader
Colas Group has been working with the CEA for many years. Faced with staffing
shortages and excavation-related risks, the company turned to CEA-Leti in
2019 for a detection solution operable by all Colas employees.
The result is a simple, accurate subsurface mapping technology for civil
engineering projects that leverages algorithms rather than operator
interpretation of images, reducing human error. The solution is now being
field-tested by Colas, and the technology is ready for development for new
use cases, such as defense.
