基于DSP和FPGA的射频雷达信号模拟器

摘要

In order to meet the rapid development of modern radar technology and the follow up of electronic countermeasure equipment,a radio frequency radar signal simulator based on DSP and FPGA is designed,Based on software radio,combi-ning physical hardware with software simulation,a improved DDS frequency on the key points is proposed to improve the precision.The simulator has good stability,programmability and scalability,can be used in electronic countermeasure envi-ronment simulation.%为满足现代雷达技术的快速发展及跟进电子对抗设备，设计了一种基于 DSP 和 FPGA 的射频雷达信号模拟器。基于软件无线电的设计思路，采用硬件实物和软件仿真相结合的方式，提出一种改进型 DDS精度，以提高关键频点。该模拟器具有较好的稳定性、可编程性和可扩展性，适用于当前电子对抗环境的信号模拟。
