← ScienceWhich risk increases when a phased array radar's output power exceeds the dielectric breakdown limit of air?
A)Increased Faraday rotation magnitude
B)Localized atmospheric electromagnetic interference✓
C)Reduced antenna side-lobe radiation
D)Enhanced free-space path loss
💡 Explanation
Atmospheric electromagnetic interference rises because the dielectric breakdown limit causes ionization when exceeded; the intense electric field exceeds the air's ability to insulate, triggering electron avalanches; therefore, localized interference increases rather than alternatives like Faraday rotation, which involve polarization mechanisms and different field interactions.
