A method of error handling in a slope monitoring system that generates slope movement data from interferometric signal processing of radar images of the slope monitoring system. The error handling occurs in two steps. The movement data is corrected for changes in atmospheric conditions and disturbances are identified. It is convenient to mask the regions identified as disturbed in the display of the corrected movement data. Typical disturbances include short term disturbances, such as trucks, and long term disturbances, such as vegetation.

L'invention concerne un procédé de gestion d'erreur, utilisé dans un système de surveillance de pente générant des données de mouvement de pente à partir d'un traitement de signal interférométrique des images radar du système de surveillance de pente. Le gestion d'erreur se déroule en deux étapes. Les données de mouvement sont corrigées lorsque des changements sont identifiés dans les conditions et les perturbations atmosphériques. Il est préférable de masquer les zones perturbées identifiées dans l'affichage des données de mouvement correctes. Les perturbations habituelles comprennent des perturbations à court terme, par exemple des camions, et des perturbations à long terme, par exemple la végétation.
