Corentin Lubeigt, postdoctoral fellow at Météo-France and former TéSA doctoral student, came to present an overview and perspectives on weather radars. While his PhD thesis focused on the study of GNSS signals reflected on the ground surface (see picture), he has now turned to weather applications to apply signal processing tools to weather radars. His research topics mainly focus on the analysis and improvement of estimator performance with applications in Earth observation and physical phenomena.
