Terrain modelling by Synthetic Aperture Radar
As part of his thesis on the Synthetic Aperture Radar (SAR), Cyril Wain will carry out an imaging campaign. SAR is a form of radar that is used to create 2D images or to perform 3D reconstructions of objects or landscapes. The principle of SAR is that it uses its motion to obtain radar images with very high resolution. This type of radar is usually shipped on airplanes or satellites. The main advantage of SAR is that, unlike optical sensors, it is not sensitive to weather conditions. Indeed, the frequency band used being that of the microwaves, the waves easily cross the clouds and the rain. This kind of tool could therefore be very useful in studying the relief of a planet whose weather conditions (clouds, stormy rains, sandstorms, etc.) would not allow observation via optical sensors. The imaging campaign would allow Cyril to test his image reconstruction algorithm in real conditions.
