← ScienceWhich consequence results when a maritime radar's waveguide corrodes?
A)Increased signal reflection at joints✓
B)Decreased antenna impedance matching
C)Reduced magnetron anode current draw
D)Amplified faraday rotation of signal
💡 Explanation
Corrosion creates surface roughness causing increased signal reflection via impedance mismatch; the standing wave ratio escalates due to increased reflected power, because electromagnetic wave propagation becomes inefficient, therefore elevated signal reflection at corroded joints increases, rather than power loss or magnetron malfunction
