PhD : Characterising the internal structure of asteroids using electromagnetic imaging techniques

In this Phd thesis, we will seek to develop new imaging procedures adapted to this studied case (based on existing ones), so as to extract quantitative information on the internal structure of comets and asteroids from data that can be measured in real space experiments. These procedures will be applied to the JuRa radar, which will probe the Didymos asteroid, to prepare for the exploitation of this radar data. To this end, studies will be carried out on the choice of input parameters, on the most relevant information that can be introduced into these imaging procedures (in particular information provided by other sensors), and on the choice of quantities to be reconstructed. The procedures will be tested with experiments on asteroid analogues carried out in the laboratory, in an anechoic chamber.
The student will benefit from ongoing national and international collaborations with researchers in planetology and applied mathematics.
