← ScienceWhich risk increases when high-intensity radar emits circularly polarized waves in rain?
A)Signal attenuation from increased absorption
B)Complete depolarization via constructive interference
C)Reduced sensitivity, enhanced cross-polarization✓
D)Faraday rotation from intense magnetic fields
💡 Explanation
Enhanced cross-polarization occurs because differential scattering of incident circularly polarized waves realigns the polarization based on rain particle shape through the Mie scattering mechanism. Therefore, sensitivity decreases, rather than increases because reflection patterns alter existing polarization.
