Research on 1.06 μm Laser Atmosphere Scattering Characteristics Based on Normal Logarithm Distribution
To solve the problem that the Junge distribution widely used in atmosphere scattering calculation makes the estimation of aerosol particles distribution inaccurate near the ground, the normal logarithm distribution which can accurately describe the aerosol particles distribution near the ground is adopted. And a laser atmosphere scattering model is established to simulate and analyze the space and time characteristics of 1.06 μm laser atmosphere scattering. Results show that the scattering intensity has a trend of sharply decreasing then slowly decreasing with the increasing of off-axis distance. The detection scattering intensity mainly comes from the position near the detection point on off-axis. The peak of the detection scattering pulse has a backward movement with the increasing of off-axis distance and pulse width increases gradually.
