Abstract
A radar system transmits signals for recording the environment of a motor vehicle, and the signals are reflected back from objects in the environment. Received signals are acquired from different combinations of transmitter and receiver antennas of the system. With regard to a series of such antenna combinations having their respective phase centers ordered in a spatial direction R, the positions of the phase centers of the combinations vary periodically with the period length P in a spatial direction S that runs perpendicular to the spatial direction R. Signal processing circuitry makes conclusions about the position of an object in the spatial direction S, based on an evaluation that the received signals from the object have a phase portion that alternates with the period length P over the antenna combinations ordered as set forth above, depending on the angular position of the object in the spatial direction S.
