← TechnologyWhich communication disruption arises when atmospheric ducts form above radar antennas?
A)Extended radar range detection
B)Signal fading and path loss✓
C)Reduced atmospheric backscatter
D)Increased antenna sidelobe interference
💡 Explanation
Signal fading develops because atmospheric ducts trap and guide radar signals over extended distances, causing destructive wave interference via the Fresnel zone. Therefore, path loss increases rather than causing the desired signal enhancements or altering antenna characteristics.
