Interferometric synthetic aperture radar(InSAR) is a promising recent technique for the generation of digital elevation models and/or the measurement of ground surface deformations. In InSAR data processing, the first step is the image co-registration, achieved by using a set of tie points which are the conjugate image points on the master and slave images. Tie points are selected with the aim of finding the conjugate point automatically on the slave image for any given point on the master image, by the process known as image matching. To achieve reliable matching, a set of points within a window is used instead of a single point. The size of the window will affect the reliability of matching. Hitherto there have been no effective methods for the determination of optimum window size for this purpose. In practice, this parameter is determined by experience.  2, record 1, English, - image%20co%2Dregistration

La mise en correspondance d'images vise à aligner deux ou plusieurs images d'une même scène, acquises par un même ou plusieurs instruments différents (optique visible ou infrarouge, radar, lidar). Une fois recalées, ces images peuvent être fusionnées. Ainsi, la combinaison des informations multi-sources, multi-vues, structurelles, statistiques, temporelles, permettra de faciliter l'analyse et contribuera à une meilleure prise de décision pour la reconnaissance des objets ou des matériaux.  2, record 1, French, - mise%20en%20correspondance%20d%27images

A relatively new technique that garners best results over urban and semi-arid regions, Interferometric SAR(INSAR) allows users to map and monitor very subtle changes in surface movement, whether it be vertical movement of the surface or structural movement through subsidence or lateral movement of a glacial floe.  4, record 2, English, - synthetic%20aperture%20radar%20interferometry

la technique d'interférométrie SAR (InSAR) consiste à [établir] la différence entre deux images radar (satellitaires ou aéroportées) acquises soit a deux points de vue différents soit à des instants différents. L'hypothèse fondamentale est que la contribution interne, liée aux propriétés physiques, géométriques et diélectriques des cibles, demeure stable entre les deux prises de vue. Si cette hypothèse est vérifiée, alors l'interférogramme révèle des systèmes de franges liés à la topographie (sensibilité de quelques dizaines de mètres dépendant de l'écart orbital entre les prises de vue) ainsi qu'à la déformation de surface (précision de quelques mm).  8, record 2, French, - interf%C3%A9rom%C3%A9trie%20par%20radar%20%C3%A0%20synth%C3%A8se%20d%27ouverture

Using the INSAR technique, it is possible to produce directly from SAR image data, detailed and accurate three-dimensional height maps of the Earth's surface topography. In addition, an extension of the basic technique, known as Differential INSAR(DINSAR), allows the detection of very small(centimetre-scale) motion of the land surface within an image. Furthermore, INSAR is emerging as a powerful tool for the detection of changes of land surface through the use of phase coherence. These possibilities open up many new potential applications of space-borne SAR data in the areas of cartography, volcanology, geomorphology, ice/glacial motion and land surface classification.  3, record 3, English, - interferometric%20synthetic%20aperture%20radar%20technique

The interferometric SAR(InSAR) technique has emerged as a precise approach to the extraction of high-resolution elevation data and measurement of small surface motion based on the phase information derived from the complex radar images. SAR interferometry combines complex radar signals recorded by the antenna at a slightly different location to measure the phase differences between the complex radar images....
