Titre :<\/strong> \u00a0\u00bb Nouveaux Algorithmes d\u2019estimation de phases pour l’Interf\u00e9rom\u00e9trie SAR multi-temporelle\u00a0\u00bb<\/p>\n

Mots cl\u00e9s :<\/strong> matrice de covariance, estimation robuste, InSAR multi-temporel, Phase Linking, s\u00e9ries temporelles, mesure de d\u00e9placements<\/p>\n

R\u00e9sum\u00e9\u00a0<\/b>:Cette th\u00e8se s’int\u00e9resse au domaine de l’interf\u00e9rom\u00e9trie SAR multi-temporelle (MT-InSAR), qui permet de d\u00e9terminer avec pr\u00e9cision le d\u00e9placement d’un objet. Plus particuli\u00e8rement, cette th\u00e8se se concentrera sur les algorithmes d’estimation de la phase, qui permettent d’obtenir ces mesures de d\u00e9placement pr\u00e9cises. Suite au volume sans pr\u00e9c\u00e9dent de donn\u00e9es SAR en libre acc\u00e8s, la demande d’un algorithme \u00e0 faible charge de calcul a augment\u00e9, permettant l’analyse d’une s\u00e9rie temporelle plus longue sur une couverture plus large. De plus, les missions r\u00e9centes offrent une source de donn\u00e9es \u00e0 haute r\u00e9solution qui n\u00e9cessite des algorithmes capables de garantir la pr\u00e9cision de l’estimation tout en conservant la r\u00e9solution spatiale. Ainsi, en r\u00e9ponse \u00e0 ces d\u00e9fis, nos objectifs sont doubles : i) formuler et d\u00e9velopper un cadre math\u00e9matique o\u00f9 l’estimation de la phase est reformul\u00e9e en un probl\u00e8me d’optimisation de l’ajustement de covariance ; ii) introduire un cadre d’estimation robuste pour ce probl\u00e8me d’estimation de phase. Les performances des algorithmes propos\u00e9s sont analys\u00e9es \u00e0 l’aide de simulations et d’une \u00e9tude de cas sur des donn\u00e9es r\u00e9elles concernant la ville de Mexico.<\/p>\n
