摘　　要：本文设计了一种基于AD9361的雷达干扰信号模拟器,利用宽带射频收发器AD9361和FPGA构建灵活的硬件平台,通过软件无线电的合理设计完成对各种雷达干扰信号的模拟。从射频收发和基带数据处理角度对雷达干扰信号模拟器进行设计。射频收发以AD9361为核心,实现射频模拟信号的收发及其与基带数字信号之间的转换功能;基带数据处理以FPGA为核心产生多种基带雷达干扰信号,并完成对AD9361的控制。测试结果表明,该模拟器可成功产生多种常见雷达干扰信号,为雷达和雷达对抗以及相关专业学生的教学和实验提供了良好的实验环境。A radar jamming signal simulator based on AD9361 is designed. The simulator uses a wideband RF transceiver AD9361 and FPGA to establish a flexible hardware platform and complete the simulation of various radar interference signals through the rational design of software radio. The radar jamming signal simulator is designed from the perspective of RF transceiver and baseband data processing. The RF transceiver uses AD9361 as the core, which realizes the transmission and reception of RF analog signals and the conversion function between them and the baseband digital signals. The baseband data processing uses FPGA as the core to generate a variety of baseband radar interference signals and control the AD9361. The test results show that the simulator can successfully realize a variety of common radar jamming signals, and can provide a good experimental environment for the teaching and experiment of radar and radar countermeasures as well as for the students of related majors.
