摘　　要：针对雷达实验仪器昂贵稀少难以开展实验教学的问题,基于中频信号,通过DSP与FPGA构建了一种低成本雷达原理实验仪,模拟产生雷达发射信号、目标回波,实现中频信号采样、信号检测与数据处理功能,并能与上位机(PC)进行通讯,完成实验参数的设置,显示雷达处理结果。本文给出了设计指标、构成方案和主要功能的设计实现过程,能为通用雷达信号处理平台研制提供参考。Aiming at the problem that＇ s hardly to develop experimental teaching because of the rare and expensive radar experimental devices, a new experiment instrument of radar principle with DSP and FPGA based on intermediate frequency signal is studied. The Instrument could simulate the emissive and echo signal, implement sampling and detections, and communication with PC. Therefore, it can implement the parameters setting, display the result of data processing. Parameters, overall scheme and the realization of main function are designed systematically. It provides meaningful reference for development and application of the radar signal processing platform.
