Abstract: A method for operating a detection device for determining distance variables in which distances characterise objects detected by the detection device is disclosed. From at least one amplitude-modulated electrical send signal at least one scanning signal is generated, which is sent into at least one monitoring region of the detection device. From at least one echo signal of at least one scanning signal reflected in the at least one monitoring region at least one amplitude-modulated electrical receive signal is determined. From at least one electrical send signal and at least one electrical receive signal at least one distance variable is determined. When determining the at least one distance variable at least one adjustment is carried out. A temperature adjustment is carried out in which at least one temperature adjustment variable is applied to at least one distance variable.

Abstract: A receiving device of a detection device for monitoring a monitoring region for objects using electromagnetic scanning signals is disclosed. The device has a signal converting means for converting electromagnetic signals originating from electromagnetic scanning signals into electric signals and a frequency analyzing means for analyzing the frequency of signals. The frequency analyzing means has at least one spectral analyzing means, by which magnetic signals are analyzed to form at least one electromagnetic spectrum that is output in a spectrum output range of the at least one spectral analyzing means. At least two signal converting means, by which separate electric signals are ascertained, are assigned to different sections of a spectrum output range of the spectral analyzing means. The different sections of the spectrum output range correspond to different frequency ranges of an electromagnetic spectrum.
