基于脉冲法的高速测距技术研究

基于脉冲法的高速测距方法中,速度和精度不能兼得。采用低通滤波的方法,实现了采样速度在2000Hz,测距范围在20m范围的情况下,测距精度在±4mm的目的。大范围、高精度、快速地测距模块可以大大提高航空航天、大地测量、船舶制造等领域的技术水平。

Study of High-speed Distance Measurement Based on Pulse Method

High-speed distance measurement on basis of pulse method is hard to achieve both rate and accuracy.This paper in- troduces low-pass filtering to achieve the purpose that ranging accuracy is ＋4ram,when range is 20m,and sampling fre- quency is 2000Hz.Wild-range,high-accuracy,and high-speed ranging module can greatly increases technology level of the field of Aerospace,Geodetic,Shipbuilding and so on.
