Beschreibung
Zusammenfassung:	A radar sensing system for a vehicle includes a radar sensor having a plurality of transmitting antennas and a plurality of receiving antennas. The transmitting antennas and the receiving antennas are arranged in multiple rows and columns of transmitting antennas and multiple rows and columns of receiving antennas. A control controls radar transmission by the transmitting antennas and receives outputs from the receiving antennas. The control applies two dimensional multiple input multiple output processing to outputs of the receiving antennas. With two dimensional multiple input multiple output processing applied to outputs of the receiving antennas, the transmitting antennas and the receiving antennas achieve an enhanced two dimensional virtual aperture.
