Patent attributes
A MIMO radar sensor is described for motor vehicles as including an antenna array, which is angle-resolving in two directions perpendicular to each other and including multiple receiving antennas, which are situated offset from one another in a first of the two directions, and multiple transmitting antennas, and including a control and evaluation unit for activating the transmitting antennas and for evaluating signals of the receiving antennas. The antenna array includes at least three selectively activatable transmitting antennas, which are offset from one another both in the first direction as well as in the second direction, and the control and evaluation unit is designed for a two-dimensional angle estimation in the first direction and the second direction using the signals received when the transmitting antennas are activated differently.
