    Abstract: A sensing system for a vehicle includes at least one radar sensor disposed at the vehicle and having a field of sensing exterior of the vehicle. The at least one radar sensor includes multiple transmitting antennas and multiple receiving antennas. The transmitting antennas transmit signals and the receiving antennas receive the signals reflected off objects. Radar data sensed by the at least one radar sensor is received at a control, and a vehicle motion estimation is received at the control. The control, responsive at least in part to the received sensed radar data and the received vehicle motion estimation, generates a surface model representative of the surface along which the vehicle is traveling.

    Abstract: A sensing system for a vehicle includes at least one radar sensor disposed at the vehicle and having a field of sensing exterior of the vehicle. The at least one radar sensor includes multiple transmitting antennas and multiple receiving antennas. The transmitting antennas transmit signals and the receiving antennas receive the signals reflected off objects. Multiple scans of radar data sensed by the at least one radar sensor are received at a control, and a vehicle motion estimation is received at the control. The control, responsive to received scans of sensed radar data, detects the presence of one or more objects exterior the vehicle and within the field of sensing of the at least one radar sensor. The control, responsive to the received scans of sensed radar data and the received vehicle motion estimation, matches objects detected in the scans and determines angles toward the detected objects.

    Abstract: A vehicular sensing system includes a radar sensor having a field of sensing exterior of the vehicle, a plurality of transmitters that transmit radio signals, a plurality of receivers that receive radio signals. The radar sensor includes a first ADC, a second ADC, a DAC and a subtractor. The first ADC converts an analog input signal derived from the received radio signals into a first number of bits. The DAC converts the first number of bits into a first analog signal. The subtractor subtracts the first analog signal from the input signal to determine a second analog signal. The second ADC converts the second analog signal into a second number of bits. The first and second numbers of bits are appended to establish a total number of bits that represent a digital value of the voltage of the analog input signal.

    Abstract: A sensing system for a vehicle includes at least one radar sensor disposed at the vehicle and having a field of sensing exterior of the vehicle. The radar sensor includes multiple transmitting antennas and multiple receiving antennas. The transmitting antennas transmit signals and the receiving antennas receive the signals reflected off objects. Multiple scans of radar data sensed by the radar sensor are received at a control, and a vehicle motion estimation is received at the control. The control, responsive to received scans of sensed radar data, detects the presence of objects within the field of sensing of the radar sensor. The control, responsive to the received scans of sensed radar data and the received vehicle motion estimation, synthesizes a virtual aperture and matches objects detected in the scans and determines a separation between detected objects by tracking the detected objects over two or more scans.
