This thesis presents efficient SAR raw data simulation. Initially, the case of a linear sensor trajectory is considered and it is shown that raw data simulation can be considered as inverse raw data processing. Different examples are presented with a point scatterer using inverse Omega-k and inverse Chirp Scaling algorithm. Raw data simulation corr...
The goal of the thesis is the analysis of audio signals using sinusoidal modeling. The first part of the thesis deals with the estimation of the sinusoidal parameters, and in particular with the methods based on the Fourier Transform. The advantages of this family of methods are a low algorithmic complexity and an ease of use. A complete state of t...

Civil Aviation standardisation bodies (ICAO, RTCA, EUROCAE) are currently investigating the use of the Global Navigation Satellite System (GNSS) as a stand-alone navigation solution for civil aircraft. For obvious safety reasons, on-board GNSS receivers must guarantee minimum performance requirements in given phases of flights. These requirements, ...
Cette thèse présente une étude expérimentale de la fluorescence induite par laser analysée par un spectromètre à transformée de Fourier haute résolution de la molécule KLi. Des courbes de potentiel précises ont été calculées pour l'état fondamental, X1 +, de 39K7Li et 39K6Li. Une étude simultanée de ces deux isotopologues a établi une brisure de l'...
