Abstract :
In this paper, we briefly analyze characteristics of linear frequency modulation (LFM) signal, stepped frequency signal and stepped chirp signal which are employed as high-range resolution radar signals. Then we propose a design of frequency synthesizer based on a new direct digital frequency synthesizer (DDS) which clock frequency is up to 3.2 GHz. The frequency synthesizer can generate three kinds of high-range resolution radar signals, which output bandwidth is up to 1.6 GHz. Through up-conversion, the frequency synthesizer can be used in many wave bands.
