← ScienceWhich outcome impairs radar performance when ice accumulates?
A)Reduced electromagnetic wave transmission✓
B)Increased antenna mechanical resonance
C)Enhanced atmospheric signal scattering
D)Elevated impedance signal amplification
💡 Explanation
Electromagnetic waves are attenuated due to dielectric changes. Ice introduces parasitic capacitance, causing impedance mismatch by hindering the complete signal transmission because ice absorbs RF energy. This causes signal blockage in the electromagnetic spectrum, rather than impedance amplification or resonance.
