New concept of passive measure using GNSS reflected signals in oceanographic applications
Résumé
Today, one of the methods in monitoring oceans is the use of radar systems or more generally the use of electromagnetic diffusion. Thanks to the deployment of satellite navigation systems (GNSS), such as GPS, GNSS signals are being used more and more as an opportunity source for this kind of observation. This paper assesses the measurement of oceanographic parameters within a few meters near the surface. The oceanographic phenomena that is currently available for recording is limited. That is why we propose a much finer analysis of the diffusion and the scattering of GNSS signals near ocean surface, by employing very fine time steps and integration over the long periods of code. The final goal is to be able to perceive very fine phenomena, among which the ocean surface kinematics. In order to achieve this, the application of sophisticated processing algorithms is needed. In this work we simulate and highlight the observable effects expected as a result of use of such a method. The work is realized as a part of the MOPS project.
