Abstract:
Device for generating a desired transit time delay T between a pulsed radar signal arriving at the device and an associated pulsed radar signal present at an output of the device, in particular in the microwave range, wherein the transit time delay T corresponds to a certain transit distance S of the pulsed radar signal, characterized in thata) a delay line comprising a signal input and a signal output for the pulsed radar signal is provided, whose transit causes a time delay &tgr; of the pulsed radar signal between its input at the signal input of the delay line and its output at the signal output of the delay line, b) a signal amplifier with a signal input and a signal output for the pulsed radar signal is connected downstream of the signal output of the delay line, wherein the signal amplifier increases the amplitude of the pulsed radar signal arriving at the signal input of the signal amplifier by a certain amplification factor f, and c) 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 into the signal input of the delay line again, and which permits after n-fold transit of the pulsed radar signal through the delay line and the signal amplifier, decoupling of at least part of the amplitude of the pulsed radar signal to the output of the device, wherein T=nÂ·&tgr; and wherein n is a natural number.
