The WISDOM ground penetrating radar is one of the instruments onboard the rover of ESA and ROSCOSMOS ExoMars 2020 mission. Its objective is to seek out traces of past or present life in the shallow Martian subsurface. To achieve this goal, the rover is equipped with a 2 m long drill, able to retrieve underground samples. WISDOM will give useful insights on the structure and dielectrical properties of the subsurface to guide drilling operations. In this context, the vertical resolution of the radar is key. In order to improve this resolution, bandwidth extrapolation techniques are applied to both synthetic and experimental WISDOM data.
