| 摘 要： | 为了提高大气能见度的仪器探测水平,并验证自行研制的车载式拉曼激光雷达探测大气水平能见度的可靠性,使用1种基于可见光波段的前向散射能见度仪,与基于后向散射原理的拉曼激光雷达进行了联合试验,对两者测量结果,进行了分析和讨论,结果表明这两种探测手段具有较高的相关性.同时,通过对前向散射原理的探讨,为能见度仪的国产化提供了参考,也检验了国内首台车载式拉曼激光雷达在测量能见度方面的可靠性,扩展了它的应用领域.

| Abstract: | Two types of methods of measuring atmospheric horizontal visibility are presented. One is based on a band of visible optical forward scattering visibility sensor; the other method is based on the theory of backward scattering of lidar. The contrast analysis and discussions of the two measurement results reveal that the two detectible methods are coherent, It is proven that the first mobile Raman-lidar for the measurement of visibility is reliable ,therefore,the application field of the mobile raman lidar is expanded. |
