| Abstract: |
| We consider the propagation and scattering of waves emitted from synthetic aperture radar located in the dry air over a vast layer of sea ice. The wave length is much smaller compared to the mean free path of the air but much larger than the correlation length of the medium inhomogeneities in the sea ice. By combining homogenization theory and kinetic limits techniques, we derive models for the scattered wave measured at the radar. Several inverse scattering problems will be considered, which concern the statistics of the inhomogeneities of the sea ice, the depth of the sea ice, etc. This talk is based on joint work with Olivier Pinaud. |
