激光成像雷达成像仿真技术研究

Study for the techniques of lidar imaging simulation

提出了一种模拟激光戍像雷达图像的新方法,该方法基于激光成像雷达的基本工作原理,结合激光在大气传输过程中的消光效应和激光成像雷达的光电噪声,对整个成像过程进行了高精度模拟.实验结果表明,该方法仿真的激光回波波形与实测波形比较接近,仿真得到的图像具有较高的可信度,并且已经在激光成像雷达样机设计和后继的匹配定位导航研究中得到应用.

A new arithmetic is imported to simulate the Image laser radar in this paper.This arithmetic is base on lidar's basic operating principles;meanwhile,the extinction effects of laser transmission in the atmosphere and lidar's PV noise are considered,and so to accurately simulate the imaging processing of the lidar.The experimental results show that the reflected wave of simulation is very similar to the actual waves measured by oscilloscope,and the simulative images have good accuracy and credibility,which has been used in radar designing and image matching navigation.
