Abstract: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.
