Hi,
detect small breaches in the hull
Have you read the paper you point to? Do you understand what is being done, and what measurements are being made? Do you understand something about "signal processing"?
The paper you pointed to is related to measuring the forces and deflections on a boat hull. There are no instances of "breaches" in the hull that I see; that would happen in an unusual damage event.
Exactly what do you want to accomplish?
