基于FPGA+PC104的雷达目标模拟器设计

摘要

A method of simulating radar echo signal with the embedded system based on PC 104 and FPCA is introduced. The article particularly discusses the hardware realization method of radar parameter collection and target signal generatin based on FP-GA. Then the theory of generating theoretic flight path and realise calculation and control of target parameters with PC 104 is analysed. At last,the signal generation simulator is online tested and the results prove that this system can generate radar target and in-terferer signal realistically and is of simple structure,easy control and strong flexibility.The simulator can be used in the real equipment training and radar debugging.%介绍了一种基于PC104与FPGA构成的嵌入式系统来模拟雷达回波信号的方法.给出了以FPGA为核心采集雷达参数以及产生雷达目标和干扰信号的硬件实现方法,分析了通过PC104产生理论航迹和进行目标参数计算与控制的实现流程.测试结果表明,该模拟器能够逼真地实现雷达空情目标及干扰信号,且具有结构简单、控制方便、灵活性强的优点,可用于实装训练和雷达调试.
