← ScienceWhich risk increases when a radar dome's dielectric constant is mismatched?
A)Radar signal propagation path distortion✓
B)Increased antenna element thermal expansion
C)Decreased waveguide dielectric breakdown
D)Erosion due to increased static discharge
💡 Explanation
Radar signal's refraction increases due to impedance mismatches. This occurs because Snell's law dictates path deviation based on varying refractive indices during propagation, therefore, increased path distortion, rather than thermal, electrical, or localized effects, results.
