Abstract
A radar sensing system for a vehicle, the radar sensing system including a transmitter and a receiver. The transmitter is configured to transmit a radio signal. The receiver is configured to receive the transmitted radio signal reflected from objects in the environment. The transmitter includes an antenna and is configured to transmit the radio signal via the antenna. The antenna includes a plurality of linear arrays of patch radiators. An arrangement of the linear arrays of patch radiators is selected to form a desired shaped antenna pattern having a desired mainlobe shape and desired shoulder shapes to cover selected sensing zones without nulls or holes in the coverage.
