← ScienceWhat outcome develops during satellite communications when signal propagates amidst atmospheric disturbances?
A)Signal phase experiences rapid scintillations✓
B)Amplifier thermal runaway risk peaks
C)Antenna gain improves constructively
D)Carrier frequency immediately stabilizes lower
💡 Explanation
Ionospheric irregularities cause disturbances, so radio waves undergo rapid constructive and destructive interference—ionospheric scintillation— because fluctuations generate rapid phase and amplitude changes. Therefore, phase scintillations occur, rather than signal improvement, because diffraction spreads the waves.
