Abstract
A processing system for processing signals from a plurality of transducers of an ultrasonic sensor in order to determine characteristic information relating to an object detected by the ultrasonic sensor is provided. The system comprises a coupling device for transforming the signals received from the transducers into pulses, and a pulse processing unit for determining the characteristic information based on the pulses delivered by the coupling device. The coupling device comprises: a thresholding unit for applying, for each signal received from a transducer, thresholding to a signal derived from the signal received from the transducer and extracting directional information contained in the phase of the derived signal; a transformation unit for transforming the derived signal into pulses containing the phase of the signal, using the information extracted by the thresholding unit.
