Abstract |
AB |
[EN] In a coherent pulse radar system supported by a spaceborne or airborne platform (S) imaging a ground swath by its antenna at nearly constant flight velocity, particularly a synthetic aperture radar (SAR) in addition to the yaw angle also the pitch angle is steered to such an extent that the Doppler centroid is reduced to 0 Hz independent of the incidence angle. For use in Earth remote sensing.
[FR] L'invention concerne un système radar cohérent à impulsions appuyé par une plateforme spatiale ou aérienne (S) d'imagerie d'une bande sol balayée par son antenne à une vitesse de vol presque constant, en particulier un radar à synthèse d'ouverture (SAR). En plus de l'angle de lacet, l'angle d'attaque est dirigé de telle sorte que le centroïde Doppler passe à 0 Hz, peu importe l'angle d'incidence. Application pour la télédétection de la Terre. |
