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.
