Abstract
A method for simulating echo signals for Doppler radar systems having a radar signal transmitted by a first Doppler radar system and received by a second Doppler radar system wherein the signal is subjected to the action of a Doppler frequency shift based upon switching of either an antennae changeover switch or a transmitting and receiving changeover switch at a frequency equivalent to the Doppler frequency shift to be generated and sent back as a simulated echo signal.
