Beschreibung
Zusammenfassung:	A vehicular radar sensing system includes at least one radar sensor having a plurality of transmitting antennas and a plurality of receiving antennas. Individual transmitting antennas are arranged in multiple rows, and individual receiving antennas are arranged in multiple columns. The multiple rows of transmitting antennas include first and second rows of transmitting antennas, each row having at least four transmitting antennas. Each column of the multiple columns of receiving antennas comprises at least four receiving antennas. The multiple columns of receiving antennas are disposed between the first row of transmitting antennas and the second row of transmitting antennas. The vehicular radar sensing system applies two dimensional multiple input multiple output processing to outputs of the receiving antennas. The vehicular radar sensing system, responsive to processing of outputs of the receiving antennas, detects objects present in a field of sensing of the at least one radar sensor.
