摘要
结合FPGA嵌入式系统高并行度和控制简单的特点,采用基于可编程逻辑门阵列(FPGA)的直接数字合成(DDS)技术编程实现了雷达信号的模拟,并以雷达线性调频脉冲信号和雷达视频信号的模拟为例,分析了该方法实现雷达信号模拟的原理及具体过程。最后,给出了雷达信号模拟的部分实验结果,并与DDS专用芯片的方法进行了详细的比较。
With the advantage of FPGA embedded system in parallel signal processing and controlling, radar signal was simulated with DDS on FPGA. LFM and video signal were taken as the example. The theory and process of radar signal simulate were analyzed in detail. Some results were given in the end, and it was compared with the DDS method.
