Job description: Numerical Modeling of the electromagnetic scattering by a sea surface
The observation of the ocean surface using electromagnetic sources of opportunity (GNSS signals for instance - GPS or GALILEO) constitutes a green research topic for several years. Indeed, different American and European research teams have recently developed passive airborne or satellite systems that can observe the reflexion of the GNSS signals by the ocean surfaces. And, the so obtained results show that the GNSS signals provide a relevant source of opportunity for the sea surface monitoring. In the case of a GNSS observer situated at few dozens of meters above the sea, there are very few operational passive systems and the measured information usually remains sparse (sometimes limited to the sea level monitoring).
Yet, in the vicinity of the sea surface, our recent simulation studies have shown that the scattered GNSS is significantly influenced by the time evolving sea surface. These results suggest that the scattered GNSS signals are for the moment not used to their maximum. Innovative signal processing algorithms and new inverse problem methods could most certainly transform the GNSS receivers as a very powerful source of advanced oceanographic information.
The "Extraction et Exploitation de l'Information en Environnements Incertains" Laboratory (E3I2) at ENSIETA invites applications for a PhD graduate research position. This PhD position concerns the electromagnetic simulations of the GNSS signals scattered by a sea surface (dynamique model).
Candidates should have a broad knowledge in electromagnetism and a strong interest in theoretical and computational work. Interested applicants should submit a CV and a description of research interests, and arrange for two letters of recommendation to be sent on their behalf.
