摘要
介绍了激光信号通过随机的大气信道时大气中气体分子对激光的吸收,探讨了大气中的气溶胶粒子对大气的散射效应以及大气的湍流对光信号的影响,并用MATLAB进行了仿真,针对仿真结果和实际情况存在的偏差,分析了产生偏差的原因。
This paper introduces the absorption of the gas molecules in atmosphere on the laser when the laser signal passes through the random atmospheric channel, probes into the scattering effect of the aerosol particles in atmosphere on atmosphere and the influence of atmospheric turbulence on the analyzes on the optical signal, and makes simulation with MATLAB, and in the light of the declination between the simulating result and actual situation, analyzes on the reasons of the generation of the declination.
