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.
Claims12
An angle-scanning radar system comprising:
- an analog beam-shaping network in a transmitting direction;
- a group antenna including a plurality of radiator elements;
- a coupling device to operate the group antenna in both the transmitting direction and a receiving direction;
- a device to form a mixed baseband signal by mixing radar receiving signals and radar transmitting signals;
- and
- a unit for generating radar signals, including the beam-shaping network, to split an oscillator transmitting signal into N paths having at least one of a corresponding phase weighting and an amplitude weighting.
