Abstract

This invention refers to a system for ultrasonic detection, particularly for applications on motor vehicles or the like, comprising at least one capsule which is equipped with at least two transducer elements suitable for the transmission, with the same frequency, of respective ultrasonic signals and for the reception of echo signals reflected by at least one obstacle for the definition of a single operative lobe, independent piloting means of each of said transducer elements suitable for the regulation of at least one between the phase and amplitude of the transmitted ultrasonic signals and received echo signals for varying the orientation and/or form of the operative lobe, and at least one management and control unit operatively associated with the piloting means and suitable for the parametric evaluation of the received echo signals for the determination of the presence and/or position of the obstacle. The method for ultrasonic detection, particularly for applications on motor vehicles or the like, comprises a transmission stage, with the same frequency, of at least two ultrasonic signals and a reception stage of echo signals reflected by at least one obstacle for the definition of a single operative lobe, a regulation stage of at least one between the phase and the amplitude of each of the transmitted ultrasonic signals and received echo signals for varying the orientation and/or form of the operative lobe, and a parametric evaluation stage of the received echo signals for the determination of the presence and/or position of the obstacle.
