Short summary
We studied how to locate damage in metal plates when only a few sensor measurements are available. Our method first combines the limited signals in a more reliable way and then sharpens the damage image with a guided learning step. Tests using laboratory measurements and supporting simulated data showed clearer images and more accurate locations. This could make structural inspection more reliable when data are scarce.
