目前,国内民航机场气象自动观测系统云高仪部分多采用芬兰VAISALA公司的CT12K激光测云仪。该设备具有可靠性高,测量数据准确,实时性好等优点。因为飞机进近位置上空的云高对飞行安全有直接影响,所以CT12K云高仪一般安装在跑道两头距离起飞线一公里处。现将该设备的理论基础和西安咸阳国际机场CT12K激光测云仪的实际应用介绍如下: 一、云高仪工作原理 CT12K云高仪的基本原理是:测量激光脉冲从发射、穿透大气到云层,然后返回接收机所需的时
At present, the domestic civil aviation airport meteorological automatic observation system part of the high use of Finland’s VAISALA CT12K laser measuring cloud instrument. The device has the advantages of high reliability, accurate measurement data, real-time and so on. Since the cloud height above the aircraft approach position has a direct impact on flight safety, the CT12K altimeter is normally installed one kilometer away from the take-off line at both ends of the runway. Now the theoretical basis of the equipment and Xi’an Xianyang International Airport CT12K laser measuring cloud instrument practical applications are as follows: First, the working principle of the altimeter CT12K ceilometer basic principle is: measuring the laser pulse from the launch, penetrate the atmosphere to the clouds , And then return to the receiver as needed
