Which outcome impairs LIDAR signal precision during fog?

A)Mie scattering reducing signal coherence
B)Rayleigh scattering increasing beam wavelength
C)Atmospheric absorption reducing beam intensity
D)Fresnel reflection causing signal interference

💡 Explanation

Mie scattering by fog droplets obscures LIDAR because aerosol size matches laser wavelength, therefore the coherence is reduced, broadening pulses, rather than absorption that effects range
