Negative Gradient

The effect of sound speed profile (SSP) mismatch on source localization in shallow-water waveguides with a typical negative gradient (or thermocline) is studied numerically and experimentally. The results are interpreted using a normal mode model and a ray model. It is found that a matched-field processor is insensitive to SSP mismatch for sources above the thermocline. In addition, the sensitivity of the processor to SSP mismatch increases with the depth of sources above the thermocline.
