Visibility : There are three sets of runway visual range transmissometers located at the runway of the Hong Kong International Airport. 能见度:天文台在香港国际机场跑道上安装有三套跑道视程透射表。
Lidar for Measuring Both Runway Visual Range(RVR) and Cloud Height 跑道视程(水平、斜视)和云高的激光探测
The differences due to the different descriptions of visibility terms described by various countries and international organizations are introduced, especially, the difference between meteorological visibility, visibility demanded by aviation and runway visual range. 着重介绍各种能见度术语以及部分国家和国际组织因对能见度描述用语的不同而产生的差异,尤其是气象能见度同航空要求的能见度与跑道视程之间的不同。
This paper presents a new kind of the measurement instrument for runway visual range using crossing dual light beam forward scattering method. 介绍了一种利用交叉型双光路前向散射方法实现的跑道能见度激光测量仪。
A new kind of the measurement instrument for runway visual range using laser is presented. This instrument consists of three parts : optical emitting and receiving system, signal amplifying and controlling system, and display system. 后向散射式跑道能见度激光测量仪主要由光学发射与接收系统、信号放大与处理系统及显示系统三部分组成。
