Undetected impacts can cause hidden damage to structures like aircraft.
Most current impact location systems require baseline data or information about the structure that will vary with diffeering impacts and environmental conditions. Detecting and locating impacts For example, temperature variations will vary the propagation speed of strain waves
Develop algorithms and systems for baseline free impactlocation in gerneral structures.
