The present invention provides a method to calibrate an on-board remote sensing system using a self-locking travel pattern and target remote sensing data. The self-locking travel pattern includes a number of parallel travel lines having overlapping swath widths between adjacent travel lines. The overlapping swath widths are used to determine the boresight angles and range offset of the remote sensor device. In addition, the method can be used to generate estimated horizontal and vertical displacement errors. These estimated errors can be used as correction factors for the range offset and boresight angles.

L'invention concerne un procédé de calibration d'un système de détection distant embarqué au moyen d'une structure de déplacement à verrouillage automatique et de données de détection d'une cible distante. La structure de déplacement à verrouillage automatique comprend un certain nombre de trajets parallèles de déplacement avec, entre des trajets adjacents de déplacement, des largeurs de surface balayées qui se recouvrent. Les largeurs de surfaces balayées qui se recouvrent sont utilisées pour déterminer les angles de pointage et le décalage de plage du dispositif capteur distant. En outre, le procédé peut être utilisé afin de produire des erreurs estimées de déplacements horizontaux et verticaux. Il est possible d'utiliser ces erreurs estimées comme facteurs de correction du décalage de plage et des angles de pointage.
