← ScienceWhich signal fading mechanism affects satellite communication during heavy rainfall?
A)Depolarization due to hydrometeor asymmetry✓
B)Frequency shift by Doppler effect
C)Multipath interference from ground reflections
D)Atmospheric scintillation from thermal gradients
💡 Explanation
Heavy rainfall causes depolarization because asymmetric raindrops scatter electromagnetic waves, altering their polarization state. Therefore, the intended signal fades as power distributes into unwanted polarizations, rather than frequency shifts or multipath.
