Advanced Ground Prediction System (Radar)

Radar can offer high quality imaging of the ground ahead over a relatively short distance, which is well adapted to tunnelling in a built environment. The work performed on the NeTTUN radar subsystem starts with the development of specific antennas and signal processing algorithms. A special design is required in order to achieve high performance although the system is embedded in an unfavourable environment (metallic structure, vibrations, etc.). Advanced electromagnetic simulations on modelled geotechnical configurations have been used to optimise the antenna design.
