具有水平测距功能的汽车防撞用FMCW雷达

FMCW with the Function of the Level Measuring Distance

本文介绍了一种改进的FMCW防撞雷达系统,通过安装两套系统,可以同时测出前方目标的R、V、水平距离,该系统只需在原有系统的基础上,对测量值作存储、DSP运算,便可实现,但是该系统却可以大幅度的降低雷达系统虚警率的发生,使之能够更广泛的在实际中得到应用.

An improved FMCW auto- collision radar system is introduced. R, V and the level distance of goals in the front can be measured simultaneously on the basis of installing two systems. The new system can store and operate the measurement value by DSP, which can reduce the false alert notably so as to be applied more widely.
