摘要
线性调频连续波(LFMCW)激光测距仪具有抗干扰能力强、测距准确度高的特点,距离测量误差依赖于中频信号频率的估计精度,文章采用数学建模的方法对测距仪性能进行了系统量化分析,针对分析结果进行了实际验证,并提出了提高测量准确度的措施。
LFMCW laser rangefinder has strong anti-interference capability and high precision characteristics. This paper adopts the method of mathematical modeling to make system quantitative analysis on the properties of linear frequency modulated continuous, wave laser rangefind- er. Based on the analysis results,the method for improving the measurement accuracy is put forward.
