Verfahren zur Bestimmung der Zwischenfrequenzenabweichung bei Frequenz-Puls-Radarsystemen

摘要

The invention relates to a process for determining the intermediate frequency deviation from a predetermined reference frequency in a frequency pulsed radar system with the steps: timed sampling of the echo signal in such a way that several scanning values of the echo pulse of a single target are obtained at different, preferably equidistant times within the echo pulse; Doppler filtering of the scanned values thus obtained for a single target so that several Doppler signals of the same frequency are obtained from the same target, from the phase differences of which the intermediate frequency deviation is found.
