Abstract: A mathematic model of frequency shift of atmospheric Brillouin scattering light is established and the influences of the mathematic parameters,such as air temperature,air pressure,vapor pressure,on the property of Brillouin scattering have been analyzed.The result shows that the frequency shift of Brillouin scattering light is scarcely influenced by air pressure and vapor pressure,and greatly affected by air temperature.The result has some referenced value for the detection of concealed object in atmosphere.
