Beschreibung
Zusammenfassung:	An environment monitoring device in a motor vehicle having a signal generating device for generating a transmitted signal, at least one ultrasonic transducer for converting electric oscillations into acoustic oscillations and/or vice versa, and an evaluation device which evaluates an electric received signal in order to determine distances to objects in an environment of the motor vehicle, wherein the signal generating device is linked to the at least one ultrasonic transducer so that the ultrasonic transducer emits an ultrasonic transmitted signal into the environment in accordance with the electric transmitted signal, and the evaluation device is connected to the at least one ultrasonic transducer or at least one further ultrasonic transducer in order to receive the electric received signal. Also disclosed is a method for monitoring an environment by using a cross-correlation.
