Angle estimation for an automotive radar with multiple transmit and receive antennas for multipath propagation

摘要

Method for a radar system for determining an attitude angle of an object comprising the steps of: transmitting signals with a plurality of transmit antennas receiving the signals reflected at the object with a plurality of receive antennas determining a position angle of the object from combinations of received signals from different transmit and receive antennas by an angle determination method, characterized in that the angle determination method coherently processes the received signals of the same transmitting antenna and incoherently combines the coherently processed signals of the different transmitting antennas, or the angle determining method coherently processes the received signals of the same receiving antenna and incoherently incoheres the coherently processed signals of the different receiving antennas be combined.
