A motor road vehicle collision warning system (1) comprises an obstacle sensing system (3), comprising a plurality of sensors (5) together capable of sensing obstacles around the vehicle (7) and generating obstacle of concern signals when obstacles are sensed, and a warning control system (9) for receiving said obstacle of concern signals and for determining whether a collision warning signal should be generated, in which the sensing system includes at least one antenna cluster (11) mounted in the region of a corner (13) of the vehicle (7), the antenna cluster (11) comprising a radar transmit antenna (15) and two receive antennas (17,19) the transmit antenna (15) mounted between the receive antennas (17,19) a first receive antenna (17) facing towards the front of the vehicle and a second receive antenna (19) facing towards the rear of the vehicle, and means (21) to trigger the operation of the transmit antenna (15) and one or both of the receive antennas (17.19). <IMAGE> |
