Abstract :
In this paper we introduce our work on developing a Ku-band 2GHz bandwidth RF subsystem based on Stepped frequency chirp signals (SFCS) including transmitter, receiver and frequency synthesizer, as well as experimental results. Very high resolution radar image for a moving train has been obtained by using the developed RF subsystem.
