← ScienceWhich problem impacts long-range LIDAR accuracy due to atmospheric conditions?
A)Signal decorrelation reduces fringe visibility✓
B)Chromatic dispersion distorts pulse shape
C)Molecular absorption attenuates overall signal
D)Rayleigh scattering induces beam divergence
💡 Explanation
Signal decorrelation, reducing fringe visibility, limits the ability to distinguish subtle time-of-flight differences because atmospheric turbulence diminishes laser coherence during propagation into separate beams for measurement ; therefore accuracy decreases rather than overall signal attenuation issues due to absorption/particle scattering.
