摘要
基于FPGA的各种雷达信号产生方法,介绍了在FPGA中实现直接数字频率合成器(DDS)以及提高输出信号质量的方法,编程实现了频率捷变、线性调频以及相位编码等雷达信号的产生。仿真结果表明,该方法能灵活地产生多种雷达信号,且质量较好。
A new method to generate a variaty of radar signals based on the Filed Programmable Gate Array （FPGA）is pro posed. The paper presents a method to implement the Direct Digital Synthesis （DDS） in FPGA, and improve the quality of the output signals. The frequency agility radar signal ,linear frequency modulation radar signal ,phase-coded radar signal have been realized by programing. The simulation results show that the method is flexible, and the quality of signals is good.
