A Design of High-range Resolution Radar Signal Synthesizer

摘要：

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 3.2GHz. The frequency synthesizer can generate three kinds of high-range resolution radar signals, which output bandwidth is up to 1.6GHz. Through up-conversion, the frequency synthesizer can be used in many wave bands.
