Abstract

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.
