    摘要： A vehicular sensing system includes at least one MIMO radar sensor disposed at the vehicle and sensing exterior and forward of the vehicle. The at least one MIMO radar sensor includes multiple transmitting antennas and multiple receiving antennas. The transmitting antennas transmit radar signals and the receiving antennas receive radar signals. Radar data captured by the at least one MIMO radar sensor is provided to an electronic control unit (ECU). The ECU includes a processor and, responsive at least in part to processing at the ECU of provided captured radar data and vehicle motion information, determines different types of surfaces sensed by the at least one MIMO radar sensor. Responsive at least in part to processing at the ECU of provided captured radar data, the vehicular sensing system provides an output for at least one driving assist system.

    摘要： A method for detecting objects via a vehicular radar sensing system includes equipping a vehicle with a vehicular radar sensing system, the vehicular radar sensing system including a radar sensor. An analog input signal derived from received radio signals is converted, via a first ADC, into a first number of bits M. The first number of bits M is converted, via a DAC, into a first analog signal. A second analog signal is determined by subtracting, via a subtractor, the first analog signal from the analog input signal. The second analog signal is converted, via a second ADC, into a second number of bits K. A total number of bits N is established by concatenating the first number of bits M to the second number of bits K. A processor processes the total number of bits N to detect the object that the received radio signals are reflected from.

    摘要： A vehicular sensing system includes at least one radar sensor disposed at a 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 are received at an electronic control unit (ECU) and processed at a processor of the ECU. The ECU detects presence of a plurality of objects exterior the equipped vehicle and within the field of sensing of the at least one radar sensor. The ECU, responsive at least in part to processing at the processor of the received multiple scans of captured radar data and received vehicle motion estimation, tracks objects detected in the received multiple scans over two or more scans.

    摘要： 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.

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.
