[Termes IGN] Terre (planète)Résumé : (Auteur) DLR's Xband interferometric SAR system onboard the Shuttle Radar Topography Mission (SRTM) has been flown successfully in February 2000 and acquired 3660 Gbytes of raw data to be processed to a near global Digital Elevation Model (DEM) of the Earth with an absolute height accuracy of +16m. Before starting the operational processing deferent kinds of calibration and motion compensation activities based on the attitude and position data and recorded instrument housekeeping data have to be performed. The preliminary results achieved over ocean test areas show the absolute height error and the relative error from the radar noise within specification. The processing and archiving facility is operational and the complete data set will be processed and available to the customers till mid 2003.

[Termes IGN] télémétrie laser aéroportéRésumé : (Auteur) Interferometric synthetic aperture radar (INSAR) and laser altimeter (LIDAR) systems are both widely used for mapping topography. INSAR can map extended areas but accuracies are limited over vegetated regions, primarily because the observations are not measurements of true surface topography. The measurements correspond to a height above the true surface that depends on both the sensor and the vegetation. Conversely, topography from LIDAR is very accurate, but coverage is limited to smaller regions. We demonstrate how these technologies can be used synergistically. First, we determine surface elevations and vegetation heights from dual-baseline INSAR data by inverting an INSAR scattering model. We then combine sparse LIDAR observations with the INSAR inversion results to improve the estimates of ground elevations and vegetation heights. This is accomplished via a multiresolution Kalman Filter that provides both the estimates and a measure of their uncertainty at each location. Combining data from the two sensors provides estimates that are more accurate than those obtained from INSAR alone yet have dense, extensive coverage, which is difficult to obtain with LIDAR. Contributions of this work include 1) combining physical modeling with multiscale estimation to accommodate non-linear measurement-state relationships and 2) improving estimates of ground elevations and vegetation heights for remote sensing applications.

[Termes IGN] interféromètrie par radar à antenne synthétique
[Termes IGN] modèle numérique de surfaceRésumé : (Auteur) In this paper, the authors propose a ground-based interferometric synthetic aperture radar (SAR) technique for terrain mapping. It is based on a coherent continuous-wave step-frequency (CW-SF) radar moved along a linear horizontal rail. It works synthesising microwave holographic images taken from different points of view to obtain elevation maps by phase comparison. The focusing algorithm for imaging synthetic holograms and digital elevation models (DEM) is able to correct topographic distortion and phase wrap through an iterative multi-baseline procedure.
