Images of phase differences between two SAR images acquired from two repeated SAR coverages are called repeat-pass interferograms. The technique used with these data to generate digital elevation models (DEMs), deformation maps, and temporal change maps is called repeat-pass interferometry and was first demonstrated by Zebker and Goldstein at JPL. In this workshop, an introduction to interferometry will be given with the goal of giving the participants a basic understanding of the technique and the tools required to obtain good results. This will be followed by an overview of some of the recent results obtained by scientists working with RADARSAT, ERS-1/2, and JERS-1 SAR data sets. Finally, a summary of emerging applications will be given. Applications include: DEM Mapping, Earthquake Monitoring, Volcano Deformation Monitoring, Ice Dynamics, Land Subsidence Measurement and Land Surface Change Detection.

Des images de différences de phase entre deux images RSO acquises lors de deux couvertures RSO distinctes sont appelées interférogrammes sur passages répétés. La méthode appliquée à ces données pour générer des modèles numériques d’altitude(MNA), des cartes de déformation et des cartes du changement en fonction du temps est appelée interférométrie sur passages répétés et ce sont Zebker et Goldstein au JPL qui en ont pour la première fois fait la démonstration. Dans le cadre du présent atelier, on présentera une introduction à l'interférométrie dans le but de fournir aux participants une compréhension de base de la méthode et des outils nécessaires à l'obtention de bons résultats. Suivra un aperçu de certains résultats récents obtenus par des scientifiques travaillant avec des ensembles de données RSO des RADARSAT, ERS-1/2 et JERS-1. On fournira enfin un résumé des applications nouvelles dont : la cartographie sur MNA, la surveillance des séismes, la surveillance de la déformation des volcans, la dynamique des glaces, la mesure de la subsidence des terres et la détection des changements à la surface des étendues de terres.

A further use of gyroscopes is found in their employment as stabilizers, as on aircraft and ships, to keep inertial guidance systems steady despite the sometimes violent motions of the vehicles. In such cases the gyroscope is made very large and given a large amount of angular momentum. The rate of precession will then be very small, since the precession is inversely proportional to the angular momentum; this small rate of precession means that the system resists angular displacements. 4, record 9, English, - rate%20of%20precession
