  • Method for operating an ultrasonic sensor and ultrasonic sensor for implementing the method
    Patent number: 10031217
    Abstract: A method for operating an ultrasonic sensor with a housing and at least an ultrasonic converter comprising a surface for emitting and receiving ultrasonic waves, whereby ultrasonic waves are emitted towards an object at different points in time, whereby the ultrasonic waves being reflected from the object are received by the surface and whereby a signal 1, 2 is generated by the received ultrasonic waves is characterized in that the relative position of the surface with respect to the object is modified in such a way that the relative position is different at consecutive points in time and that the signals 1, 2 of two consecutive points in time are subtracted from each other. Further an ultrasonic sensor for carrying out the method is described.
