Which effect impairs LIDAR image resolution because of atmospheric effects?

A)Atmospheric coherence length reduction
B)Increased Rayleigh scattering intensity
C)Doppler shift induced broadening
D)Reduced laser pulse peak power

💡 Explanation

Atmospheric turbulence reduces coherence length via random variations in refractive index, resulting in wavefront distortions and degraded LIDAR resolution; therefore the correct answer is coherence length reduction, rather than scattering alone which is distinct even with coherent beams.
