1. A vehicular sensing system, said vehicular sensing system comprising:
at least one MIMO (multiple input multiple output) radar sensor disposed at a front portion of a vehicle equipped with said vehicular sensing system and sensing exterior and forward of the equipped vehicle;
wherein said at least one MIMO radar sensor 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 at least one MIMO radar sensor 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 at least one MIMO radar sensor as the equipped vehicle moves along a road, and based at least in part on an estimate of motion of said at least one MIMO radar sensor, determines different types of surfaces sensed by said at least one MIMO radar sensor; 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.
