摘　　要：设计了一款小型化短程零中频FMCW测距雷达系统模块化实验平台。该平台分为收发信机部分、天线部分以及数据采集3部分。收发信机部分主要分为锯齿波发生器模块、压控振荡器与功分器模块、混频器模块以及低噪声放大器模块,模块化的设计可以让学生更好地理解各个模块在整个系统中的用途。针对本雷达的工作频段、发射带宽等参数的匹配问题,让学生设计配套天线。利用声卡实现基带信号接入,运用Labview软件实现信号采集与处理。A modular experimental platform based on the FMCW ranging radar system with the miniaturized short range zero intermediate frequency is designed.The whole platform is divided into the following three parts：the transceiver,antenna and data collection.The transceiver part mainly includes the saw tooth wave generator module,voltage-controlled oscillator and power supply module,mixer module and low noise amplifier module.The modular design allows students to understand the function of each module in the entire system better.In view of the matching of parameters such as the frequency band and the transmitting bandwidth of this radar,the students can design the matching antenna.The baseband signal access is realized by adopting the sound card,and the signal acquisition and processing are realized by using the Labview software.
