Abstract
The present invention pertains to a radar device with synthetic aperture based on rotating antennae (ROSAR principle), preferably for helicopters, which operates in the millimeter-wave range and is used mainly as an obstacle radar, wherein the full synthetic aperture length can be reached already within very short distances due to the arrangement of the antennae on a turnstile. Exemplary embodiments, calculations and representations are shown and explained.
