Science

Which risk increases when aircraft rely solely on circularly polarized radar in heavy rain?

A)Reduced target detection
B)Elevated parasitic drag
C)Compressor stall onset
D)Increased sensor noise

💡 Explanation

Less backscatter occurs because depolarization effects become significant causing signal attenuation due to increased scattering from asymmetrical raindrops; therefore target visibility decreases rather than drag or sensor noise being primarily affected.
