A7.1 - Utilizing CDMA Techniques to Improve Ultrasound Based Distance Measurements

D. Glaser, St. J. Rupitsch, St. Adelhardt & R. Lerch
Ultrasound based distance measurements are widely used in industrial (e.g., filling level measurements) as well as in automotive applications. In the majority of cases, one or two ultrasound transducers (transceiver) are used to emit and receive the pressure waves. If the speed of sound in the propagation media is known, the distance can easily be calculated by the time-of-flight of the pressure waves. In this contribution, we present ultrasound based distance measurements with the aid...
