International audience; In this paper, we present quantitative image reconstructions (i.e. permittivity and conductivity profiles) from synthetic and experimental data. First, we perform the qualitative imaging for localizing the target in order to d

International audience; We present an inverse algorithm based on Level Set method and topological shape gradient for optimizing the shape of planar antenna structure or arrays from imposed constraints (e.g. desired or imposed radiation patterns, gain

International audience; In the field of road construction and maintenance, the need for information on the thickness of very thin road layers is not satisfied by means of commercial pulse GPR, due to the inability of such devices to operate over rang

This paper gives an overview of mm-Wave reflectarrays used for civil radar applications such as collision avoidance system for rescue helicopters at 94 GHz or FOD detection on airport runways at 77 GHz. Both antenna designs and examples of radar perf
