← ScienceWhich consequence results when a submarine's acoustic countermeasures saturate its own sonar during active ping propagation?
A)Bearing estimation degrades significantly✓
B)Doppler shift calculations strengthen
C)Transducer impedance perfectly matches
D)Signal phase becomes accurately predicted
💡 Explanation
Bearing estimation degrades because active countermeasures launch intense signals designed to confuse enemy sonar; the mechanism of signal jamming overwhelms the weaker returning echoes. Therefore, direction resolution drops, rather than sharpening Doppler calculations, because propagation becomes obfuscated.
