FMCW雷达系统及其前端数据采集模块设计

摘要

FMCW（frequency modulation continuous wave） radar is widely applied in automobile anti-collision systems.The development of automobile anti-collision systems in recent years is introduced.Based on a FMCW millimeter-wave radar device,the theory and framework of the system are presented.As the important parts of data acquisition module,the preamplification and analog-to-digital converter for the radar signals are designed and introduced.%（FMCW）调频连续波雷达在汽车防撞系统中得到了广泛的应用。文中对近年来国内外汽车防撞系统的发展做了阐述和比较,以FMCW毫米波雷达作为系统前端,对防撞系统的原理、结构、信号的前置放大和模数转换等关键数据采集模块进行了介绍与设计。
