摘要：A method for the processing of a frequency signal especially for utilization inthe evaluation of a distance measurement by means of pulsed electromagnetic waves orof frequency-modulated continuous waves on the basis of the radar principle. The
frequency signal is divided into at least two frequency ranges corresponding to two maincomponents of the frequency signal, the frequency signal in each of the two frequencyranges is then subjected to a separate Fourier transform, the Fourier transform appliedto the frequency signal in the first frequency range resulting in a corresponding firstcomplex time signal and the Fourier transform applied to the frequency signal in theother frequency range resulting in a second complex time signal. The second time signalis complex-divided by the first time signal which produces a third time signal, and thethird time signal is then subjected to a Fourier transfer, the result being a processedfrequency signal.
