Claim 15:
16. A vehicular radar sensing system, the vehicular radar sensing system comprising:
at least one radar sensor disposed at a vehicle equipped with the vehicular radar sensing system, the at least one radar sensor having a plurality of transmitting antennas and a plurality of receiving antennas;
wherein individual transmitting antennas of the plurality of transmitting antennas are arranged in multiple rows of transmitting antennas, and wherein individual receiving antennas of the plurality of receiving antennas are arranged in multiple columns of receiving antennas;
wherein the multiple rows of transmitting antennas comprises at least a first row of transmitting antennas comprising at least four transmitting antennas, a second row of transmitting antennas comprising at least four transmitting antennas and a third row of transmitting antennas comprising at least four transmitting antennas;
wherein the multiple columns of receiving antennas comprises at least four columns of transmitting antennas, and wherein each column of the multiple columns of receiving antennas comprises at least four receiving antennas;
wherein the multiple columns of receiving antennas are disposed between the first row of transmitting antennas and the second row of transmitting antennas;
wherein the multiple rows of transmitting antennas and the multiple columns of receiving antennas function as at least 192 virtual receivers;
wherein each transmitting antenna radiates a waveform independently of each other transmitting antenna;
an electronic control unit (ECU) comprising a processor;
wherein the vehicular radar sensing system controls radar transmission by the transmitting antennas and receives outputs from the receiving antennas;
wherein the vehicular radar sensing system applies two dimensional multiple input multiple output processing to outputs of the receiving antennas;
wherein the vehicular radar sensing system, responsive to processing at the ECU of outputs of the receiving antennas, detects objects present in a field of sensing of the at least one radar sensor; and
wherein the vehicular radar sensing system provides detection for a driving assistance system of the vehicle, and wherein the driving assistance system comprises at least one selected from the group consisting of (i) an automatic emergency braking system, (ii) a pedestrian detection system and (iii) a collision mitigation system.
