Impact imaging of aircraft composite structure based on a model-independent spatial-wavenumber filter

Ultrasonics, 2016
The spatial-wavenumber filtering technique is an effective approach to distinguish the propagating direction and wave mode of Lamb wave in spatial-wavenumber domain. Therefore, it has been gradually studied for damage evaluation in recent years.
