Which risk rapidly increases when a ship's radar emits overlapping frequencies?

A)Wave interference nullifies echo signal
B)Excessive power tube filament wear
C)Increased magnetic field coupling losses
D)Signal transmission becomes purely transverse

💡 Explanation

Wave interference creates destructive summing of returning pulses, nullifying feedback, rather than amplification, because the principle of superposition causes destructive effects when waves are 'out of phase', therefore the returning signal is blocked.
