The invention relates to a high-resolution synthetic aperture radar device (10) comprising at least one transmitting antenna (TX1-TX3) for producing and emitting radar pulses for scanning an object (12), a receiving antenna (14) for receiving the radar beams (20, 22, 24) emitted and reflected by an object, wherein the receiving antenna (14) has several sub-apertures (RX1-RX17) arranged along elevation, which form a minimum of azimuth apertures, wherein the high-resolution synthetic aperture radar device is embodied such that pulse signals (18) are emitted at irregular time intervals.
L'invention concerne un dispositif radar à ouverture synthétique haute résolution (10) comprenant : au moins une antenne émettrice (TX1-TX3) pour la production et l'émission d'impulsions radar pour le balayage d'un objet (12), une antenne réceptrice (14) pour la réception des faisceaux d'impulsions radar (20, 22, 24) émis et réfléchis sur l'objet, dispositif caractérisé en ce que l'antenne réceptrice (14) présente plusieurs sous-ouvertures (RX1-RX17) disposées le long de l'élévation et qui forment un minimum d'ouverture azimut, et en ce que le dispositif radar à ouverture synthétique est configuré de telle façon que des signaux d'impulsion (18) soient émis à des intervalles de temps irréguliers.
