Abstract
A method is disclosed for computational noise compensation for an ultrasound sensor system. The method includes acquiring multiple reference signal representations at different points in time, storing the multiple reference signal representations, acquiring a measurement signal representation by emitting an ultrasound emission signal using the ultrasound sensor and receiving an ultrasonic reception signal using the same or the other ultrasound sensor, selecting one of the stored reference signal representations, and generating a noise-compensated measurement signal representation by subtracting the selected reference signal representation from the acquired measurement signal representation.

A method for computational noise compensation for an ultrasound sensor system of a motor vehicle the method comprising:
- acquiring multiple reference signal representations at different points in time in each case by emitting an ultrasonic emission signal using an ultrasound sensor of the ultrasound sensor system and receiving an ultrasonic reception signal using the same or another ultrasound sensor of the ultrasound sensor system;
- storing the multiple reference signal representations;
- acquiring a measurement signal representation by emitting an ultrasonic emission signal using the ultrasound sensor and receiving an ultrasonic reception signal using the same or the other ultrasound sensor;
- selecting one of the stored reference signal representations;
- and
- generating a noise-compensated measurement signal representation by subtracting the selected reference signal representation from the acquired measurement signal representation.
