The Towed Array Sonar on the FFG will display SNR values for particular tracks. As long as the Noise Level remains constant, the SNR is directly proportional to received signal power.

If I am not mistaken, there is a similar feature onboard the Seawolfs.

SNR in DW does not change with noise level, at least not when you change speed (thus increase your own waterflow noise). However I did not test it with different sea states.

Edit: it does not change even with different sea states. Noise however affects detection range. SNR in DW (FFG) is simply signal strength, not signal to noise ratio.
