Vehicle radar system with shaped antennas

A vehicular radar sensing system, said vehicular radar sensing system comprising:

• a radar sensor disposed at a vehicle equipped with said vehicular radar sensing system;
• wherein said radar sensor comprises a plurality of antennas;
• wherein said plurality of antennas comprises a plurality of transmitting antennas and a plurality of receiving antennas;
• wherein said radar sensor transmits multiple outputs via said plurality of transmitting antennas and receives multiple inputs via said plurality of receiving antennas;
• wherein said plurality of antennas comprises a plurality of sets of antennas each set having an X shape, and wherein each of the X-shaped sets of antennas comprises an apex;
• a processor;
• wherein a signal feed is provided to the apex of each of the X-shaped sets of antennas;
• and
• wherein outputs of said receiving antennas are communicated to said processor, and wherein said processor, responsive to the outputs of said receiving antennas, determines presence of one or more objects exterior the vehicle and within a field of sensing of said radar sensor.
