Don't ships do that anyway? Sprint ahead, stop, listen, sprint ahead...?
To some extent, yes, but they are able to keep their sonar systems deployed. There's a pretty substantial time overhead associated with constantly hauling in and dropping out a dipping sonar.

The U.S. Navy was planning on using the AN/AQS-22 dipping SONAR on a RIB for LCS. It doesnt have to remain still, the algorithims for ownship doppler nullification have existed for decades. I mentioned AQS-22 because its already in the supply system for U.S. Navy, and it's COTS processing and other system compatibility make it attractive alternative. On a ship it would probably be called the AN/SQS-22 Variable Depth SONAR (VDS). Linear arrays cannot distinguish signals on the left from those on the right, also kown as bearing ambiguity. A reason why it isnt widely used in the U.S. Navy. Either way, VDS are out there and would be a good alternative to a hull mounted array. |

I'm inclined to listen to the guy who does it for a living vs. the armchair experts of this forum... |
