摘　　要：利用LabVIEW具有软件开发周期短、开发成本低的优势,设计了一套基于LabVIEW的雷达系统仿真软件。先后开展对雷达系统的结构分析以及模块化设计等工作,并对设计的各个模块进行分析与测试。其中,模块化设计完成了雷达收、发波形的设计以及匹配滤波、脉冲积累、MTI处理、Doppler处理和CFAR门限检测等雷达信号处理算法的实现。该雷达系统仿真软件从信号的发射、接收、处理以及显示等过程复现了整个雷达系统的工作流程,通过测试,验证了该软件功能全面、性能稳定。Since LabVIEW has the advantages of short software development cycle and low development cost, a set of radar system simulation software based on LabVIEW was designed. The structure analysis and modular design for radar system were proceeded. Each designed module was analyzed and tested. In the modular design, design of transceiving waveforms was completed, and matching filtering, pulse accumulation, MTI processing, Doppler processing, CFAR threshold detection and other radar sig- nal processing algorithms were realized. The workflow of whole radar system is reproducted by radar system simulation software, which includes signal emission, reception, processing and display. Test results show that the designed software has the advantages of comprehensive function and stable property.
