针对雷达回波信号的模拟进行了需求分析,通过比较,提出了以FPGA为核心模拟雷达回波信号的优势。文中主要阐述了基于FPGA的雷达回波信号模拟的系统构成和设计思想,详细介绍了雷达回波信号的具体设计与实现方法,以及数据的传输和处理的方式,并合理设计了目标回波数据生成流程,使系统能够灵活配置雷达回波信号的参数与实时接收雷达信号处理机的正北标志和主脉冲标志进行目标回波的生成。最后,对模拟的雷达目标回波进行了测试,结果证明该系统完全满足各项设计要求。

The requirements for the simulation of radar echo signal are analyzed in this paper. By comparison, the simulation of radar echo signal based on FPGA has the advantage over others. This paper mainly describes the system composition and design of the radar echo signal simulation based on FPGA and gives detailed introduction to the concrete design and realization method, as well as the data transmission and processing. The target echo data generation flow is designed reasonably, which makes the system be able to flexibly allocate the parameters of radar echo, the due north mark of the real-time signal processor, and the main pulse mark to generate target echoes. At last, the simulated echoes are tested and the result proves that this system meets all design requirements completely.
