Research of the Aerosol Scattering Properties Based on Evaporation Duct
Abstract：Based on Mie scattering theory,the characteristic of laser beam propagation was analyzed.The two kinds of typical condition was that of different temperature and humidity.With montecarlo method,the scattering of atmospheric aerosols was simulated,the characteristic of laser beam propagation under the two kinds of typical meteorologic condition was analyzed.It came to the conclusion that the laser beam propagation have different features whether the atmospheric duct exist or not.The detailed conclusion was that,the radius of atmospheric aerosol increased when the atmospheric humidity increased,and the peak value of the return signal decreased,the signal attenuated faster.The peak value of the return signal became stronger when the temperature increased,these indicated that detecting the atmospheric duct with laser method was probable.
