A radar transceiver (4, 5) is mounted on a pantograph (31) for scanning over a surface of interest so that sub-surface features may be investigated and imaged. A computer controls at least one stepper motor driving an X-Y scanner (34) for determining the location and operation of the pantograph. The arrangement is useful in a SAR stepped frequency continuous wave imaging system using a two-dimensional boustrophedral or random scan of the surface and analysing both amplitude and phase components of the received signal.
L'invention concerne un émetteur-récepteur radar (4, 5) monté sur un pantographe (31) pour balayer une surface d'intérêt aux fins d'explorer et de mettre en image des éléments sous-jacents. Un ordinateur commande au moins un moteur pas à pas utilisant un scanneur X-Y (34) pour déterminer l'emplacement et le fonctionnement du pantographe. Ce dispositif est utile dans un système d'imagerie SAR à fréquence étagée et onde entretenue, qui met en oeuvre un balayage bidimensionnel aller-retour ou aléatoire de la surface et analyse la composante amplitude et la composante phase du signal reçu.
