Claim 16:
17. A method of processing signals delivered by an ultrasonic sensor, the ultrasonic sensor comprising a set of transducers, at least some of the transducers of the set of transducers emitting signals or receiving echoes corresponding to a reflection of said signals by a detected object, the method comprising determining at least one characteristic item of information relating to the detected object, based on the signals received from the transducers of the ultrasonic sensor, wherein the method comprises a step of transforming the signals received from at least some transducers of the set of transducers into pulses, and a step of processing said pulses, the transformation step comprising, for each signal received from a transducer:
applying thresholding to a signal derived from said signal delivered by the transducer, to extract directional information contained in a phase of the derived signal using at least one threshold, the extracted information comprising rising edges or falling edges of the derived signal;
transforming the signal derived from the signal received from the transducer into pulses containing the phase of the signal, using the one or more signal edges extracted in the step of applying thresholding,
and the step of processing the pulses comprises determining characteristic information based on the pulses determined for all of the signals received from said transducers.
