Claim 19:
20. A vehicular sensing system, said vehicular sensing system comprising:
a plurality of MIMO (multiple input multiple output) radar sensors disposed at a vehicle equipped with said vehicular sensing system and sensing exterior and forward of the equipped vehicle;
wherein each MIMO radar sensor of said plurality of MIMO radar sensors comprises multiple transmitting antennas and multiple receiving antennas;
wherein said transmitting antennas transmit radar signals and said receiving antennas receive radar signals;
an electronic control unit (ECU) comprising a processor, wherein radar data captured by said plurality of MIMO radar sensors is provided to said ECU for processing by said processor;
wherein said vehicular sensing system, via processing at said ECU of provided captured radar data for a plurality of scans by said plurality of MIMO radar sensors as the vehicle moves along a road, and based at least in part on an estimate of motion of said plurality of MIMO radar sensors, determines different types of surfaces sensed by said plurality of MIMO radar sensors;
wherein said vehicular sensing system, responsive at least in part to processing at said ECU of provided captured radar data, distinguishes a surface of the road along which the equipped vehicle is traveling from a non-road surface adjacent to the road; and
wherein, responsive at least in part to processing at said ECU of provided captured radar data, said vehicular sensing system provides an output for at least one driving assist system of the equipped vehicle.
