Abstract
The present invention relates to a radar system having a synthetic aperture on the basis of rotating antennae. In order to achieve real-time capacity with a high discrimination despite the high data flow, reference functions are determined by a geometry module and a circuit for dividing the strip illuminated by the antennae into a specific number of range intervals. As a result of the division of the overall analysis circuit into individual modules, a complete analysis of the incoming signals can take place despite the high data flow. By signals from additional kinematics sensors integrated into the tips of the rotor carrying the antennae, the reference functions are corrected for rotor movements which deviate from the ideal orbit.
