Abstract

It has been proposed in accordance with the invention to determine the linearity of the modulated oscillator frequency of an FMCW radar by means of the Hilbert transformation and to supply a control voltage, corresponding to the deviation, to the controllable oscillator via a digital/analog converter. A control and computing unit is used to determine the linearity of the modulated oscillator frequency.
