Abstract: 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.

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.
