← ScienceWhich risk to a satellite communication signal occurs when the phased array antenna loses thermal control and coherence?
A)Signal fading due to beam misalignment✓
B)Multipath interference from reflected signals
C)Increased thermal noise in receiver
D)Reduced power transmission efficiency
💡 Explanation
Signal fading occurs because phased array antennas rely on constructive interference from many coherent sources. Thermal distortion causes phase errors, disrupting this interference, therefore misaligning the signal beam rather than causing interference, thermal noise, or affecting power.
