边界层风廓线雷达测温系统设计

On the Radio-Acoustic Sounding System(RASS)of Boundary-layer Atmospheric Profiling Radar

风廓线雷达在气象领域的应用越来越广泛,在风廓线雷达基础上增加电声测温系统(RASS)实现大气温度实时探测是一种经济有效的办法。文中介绍了已实现的某RASS系统设计,讨论了RASS测温的原理,针对RASS测温的精度、高度、影响因素等进行了性能分析,论述了系统的实现方案,最后给出了该RASS的实际测温结果和测温谱图,验证了该设计满足系统要求,能实现实时测温。

The wind profiling radar has been developed more widely recently in the atmosphere. It is a very economic and effective method to measure atmospheric temperature by using a Radio-Acoustic Sounding System （RASS） based on the wind profiling radar. According to the RASS finished in 2004, the theory of RASS and characteristics which involve precision, height, and other factors concerned about it are all discussed. The scheme of the RASS is given in detail. At last, the real measurement result and temperature spectrum figure of the RASS are shown, and prove that the system has succeed in atmospheric temperature measurement in real time.
