oa Ground penetrating synthetic pulse radar performances

Four years ago, the « Ministère de l'Equipement et des Transports », in collaboration with two other French companies (SNCF - Société Nationale des Chemins de Fer; and the RATP - Régie Autonome des Transports Parisiens) presented a paper concerning the development of a synthetic pulse radar. After demonstrating the feasibility of such a system at the end of the eighties, we have recently improved our knowledge and carried out comparisons with the pulse and synthetic radars existing on the market. The main purpose of this research is to try to improve the depth of investigation for the detection of discontinuity or cavities in the ground or in civil engineering structures.
