Abstract
An angle scanning radar system having a group antenna controlled via a beam-shaping network, a coupling device that allows the group antenna to be operated for both the transmitting and receiving directions, and a device to mix radar receiving signals with radar transmitting signals to form a mixed baseband signal, and to digitally evaluate the mixed baseband signal with regard to the solid-angle information.
