Abstract
The invention relates to a process for determining the deviation of the intermediate frequency from a given reference frequency (f.sub.R) in the case of a frequency-pulse radar system, characterized by the time-related scanning of the echo signal such that, from an echo pulse of an individual target, several scanning values are obtained at different, preferably equidistant points in time within the echo pulse, the Doppler filtering by way of the thus obtained scanning values of an individual target so that several Doppler signals of the same frequency are obtained from the same target from whose phase differences the intermediate-frequency deviation is determined.
