摘要
建立了大气布里渊散射光频移的数学模型 ,分析计算了温度、水汽压、大气压力等大气参量对布里渊散射特性的影响。结果表明 ,布里渊散射光频移受大气压、水汽压的影响很小 ,而受大气温度的影响很大。这些结果对大气中隐形目标的探测技术具有重要的参考意义。
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.
