The electromagnetic field after interaction with the asteroid depends on its physical characteristics, so it is possible to use this field to find the internal structure of the asteroid and its electromagnetic characteristics. This is achieved by solving an inverse diffraction problem. For our application (comet and asteroid), the main difficulties are due to the very large size of the target and the limited number of measurements available.
In this M2 intership, the student will work on imaging procedures adapted to the case of asteroids.
In particular, he/she will focus on structural imaging procedures and study the approximations that can be made and their impact on the reconstructed images. He/she will also work on time/frequency analysis and include it in the imaging algorithms. The inversion procedures will be tested on experiments carried out in the laboratory, in an anechoic chamber on asteroid analogues.
The student will benefit from ongoing national and international collaborations with researchers in
planetology and applied mathematics.
