摘要
介绍了基于LabVIEW编程语言开发的米散射大气激光雷达数据采集与可视化软件。 设计中利用LabVIEW调用光子计数卡(MSA300)的动态链接库,实现了激光雷达软件对大气回 波数据的实时采集与显示,根据Fernald方法即时处理回波信号并显示消光系数与回波强度时间高度显示图(THI)。 软件采集的数据直接转换并保存为ASCII码文本格式,便于数据的后期处理与分析。初步实验效果表明,软件能够对 大气回波信号、消光系数与THI图进行实时可视化显示,便于直观了解大气激光雷达连续探测的大气气溶胶和云时 空变化信息。实验表明,软件具有良好的实时性与准确性。
Abstract
The data acquisition and visualization software of Mie lidar was developed based on LabVIEW. It can acquire and display data of lidar in real time by LabVIEW calling the dynamic link library of photon counting card (MSA300). The extinction coefficient was inversed by Fernald method and displayed with time-height-indication (THI) figure. The software converts and saves the data as ASCII format to be post-processed and analyzed. Lidar experiments show that the atmospheric data, extinction coefficients and THI can be displayed in real time by the software to intuitively understand the spatial and temporal changes of the aerosol and cloud.
