Abstract
(DE)
Bei einer Anordnung zur interferometrischen Radarmessung bei einer nach dem ROSAR-Prinzip arbeitenden Einrichtung mit einer kohärenten Sendeantenne und zwei kohärenten Empfangsantennen und ihren Empfangskanälen, bei der der Wegunterschied der beiden Antennenabstände zu den gemessenen Auftreff-Punkten aus der Wellenlänge $g(l) des gesendeten Radarsignals und des gemessenen Phasenunterschiedes der Empfangsechos der beiden kohärenten Empfangskanäle berechnet werden, wird vorgeschlagen, daß diese interferometrische ROSAR-Anordnung in oder an einer rotierenden Einrichtung integriert und so positioniert ist, daß jeder relevante Bereich des zu vermessenden Areals erfaßbar ist.
(EN)
The invention relates to an arrangement for the interferometric radar measurement according to the ROSAR principle and to a device using said principle. The inventive device comprises two coherent reception antennae having two reception channels. The distance in the path between the two distances of the antennae and the measured points of impact is calculated by the wavelength $g(l) of the emitted radar signal and the measured phase difference of the receiving echo of the two coherent reception channels. According to the invention, the interferometric ROSAR arrangement is integrated in or on a rotating device and positioned in such a way that the entire area to be measured can be detected.
(FR)
L'invention concerne un système de mesure radar interférométrique pour un dispositif fonctionnant selon le principe du ROSAR, qui comporte une antenne d'émission cohérente et deux antennes de réception cohérentes et leurs voies de réception et dans lequel on calcule la différence de chemin des deux distances d'antenne aux points d'impact mesurés à partir de la longueur d'onde $g(l) du signal radar émis et de la différence de phase mesurée des échos de réception des deux voies de réception cohérentes. Le système ROSAR interférométrique selon l'invention est caractérisé en ce qu'il est intégré dans ou sur un dispositif rotatif et est positionné de sorte que chaque zone appropriée de la surface à mesurer peut être couverte.
