Abstract

A wave-based sensor system includes at least one transmitter unit configured to emit waves. The wave-based sensor system further includes at least one receiver unit configured to receive waves and to generate at least one sensor signal corresponding to the received waves. The wave-based sensor system further includes at least one interference detection unit configured to detect interfering waves and to generate at least one interference sensor signal corresponding to the detected interfering waves. The wave-based sensor system further includes a signal processing circuit connected with the at least one receiver unit and the at least one interference detection unit. The signal processing circuit is configured to correct the at least one sensor signal based on the at least one interference sensor signal, thereby obtaining at least one corrected sensor signal. Further, a sensor signal correction method of correcting at least one sensor signal is described.
