Abstract
A vehicular radar system includes a plurality of transmitting sub-arrays and a transmission power divider. The plurality of transmitting sub-arrays are symmetric with respect to a symmetry axis, and the plurality of transmitting sub-arrays are parallel to the symmetry axis. The transmission power divider, coupled to the plurality of transmitting sub-arrays, is configured to apply a plurality of phases and a plurality of amplitudes to the plurality of transmitting sub-arrays. A first transmitting sub-array, among the plurality of transmitting sub-arrays and closest to the symmetry axis, and a second transmitting sub-array, among the plurality of transmitting sub-arrays and farthest away from the symmetry axis, have a phase difference in between, and the phase difference is between 120 degrees and 180 degrees.
