A vehicle radar system according to one aspect of the present disclosure includes a first radar device, a second radar device, and a third radar device. The first radar device transmits a first radar wave for which a transmission period or a transmission frequency is different from transmission periods or transmission frequencies of a second radar wave to be transmitted from the second radar device and a third radar wave to be transmitted from the third radar device. The second radar device transmits the second radar wave for which transmission polarization or a transmission beam direction is different from transmission polarization or a transmission beam direction of the third radar wave to be transmitted from the third radar device.
