摘要
依据调频连续波激光雷达测距原理,详细阐述了三种不同类型的调频连续波激光测距雷达的基本过程,并对其测距过程进行了推导;搭建了锯齿波、三角波和正弦波三种不同类型激光测距原理验证平台,设计了调制信号产生模块,拍频仿真模块,并测定拍频后的频率值;分析了三种类型调频连续波激光雷达的适用条件和范围,为后续系统设计和硬件选型提供了参考依据。
Three different types of laser radars are introduced based on the ranging principle of FMCW （frequency modulated continuous wave） laser radar, and also the ranging procedure is deduced. The laser ranging simulation plat- form is set up for sawtooth, triangular and sine modulated wave. Based on this platform, the modules for signal genera- tion and beat signal simulation are designed and the frequency is measured from the beat signal. In the end ,the appli- cation conditions for three different kinds of FMCM laser radars are analyzed, which provides the reference for the se- lection of system and hardware design.
