摘要
通过比较Gill仪器的Winsonic 2D测风仪和螺旋浆式风速风向计05103L的实测效果,分析了超声波测风仪测风的特点。进而分析了几种超声波测风的检测机理、系统组成和设计的注意事项;同时探讨了如何解决超声波测风仪目前使用中存在的一些问题(如:全天候使用、环境影响补偿等)。最后讨论了超声波的传输特性和大气中的杂质对风速、风向测量的影响。
The characteristic of the ultrasonic wind speed and directional measurement is analyzed by test comparison between the Winsonic 2D wind monitor sensor and the 05103 wind monitor. Several kinds of test principles of the ultrasonic wind .speed and directional measurement, their composition and their design notes are discussed, Some problems existed in the present application （such as use under any weather condition and environment compensation are discussed. The measurement influence from the characteristic of the ultrasonic transmission and the impurity in the atmosphere is also discussed.
