← ScienceWhich consequence results when a submarine's cavitation level exceeds broadcast SONAR?
A)Doppler frequency shift distortions increase
B)Surface multipath interference severely degrades
C)Active jamming range unpredictably decreases
D)Acoustic signature detection range increases✓
💡 Explanation
SONAR relies on wave propagation; increased cavitation causes intensified narrowband acoustic radiation. Higher noise floor enhances acoustic signature because rectified signal amplitudes are boosted, therefore detection range increases; rather than mitigating sonar via jamming or interference.
