Abstract
A device for generating a desired transit time delay of a pulsed radar signal is characterized in that a delay line ( ) with signal input and signal output for the pulsed radar signal is provided whose transit causes time delay &tgr; of the pulsed radar signal, that a signal amplifier ( ) is connected downstream of the delay line which increases the amplitude of the pulsed radar signal by a certain amplification factor f, and that a decoupling device ( ) is provided which permits supply of at least part of the amplitude of the pulsed radar signal coming from the signal output of the signal amplifier to the signal input of the delay line again and which permits, after n times transit of the pulsed radar signal through the delay line, decoupling of at least part of the amplitude of the pulsed radar signal, wherein T=n·&tgr; and wherein n is a natural number. This device is suited also for broad-band radar signals and can principally simulate transit distances of the pulsed radar signal which have no upper limit.
