Lamb wave imaging via dual-frequency fusion for grating lobe effect compensation

•A Lamb wave imaging method via dual-frequency fusion is proposed.•This method effectively compensates for the grating lobe effect.•This method improves positioning accuracy with higher excitation frequencies. In Lamb wave imaging based on a phased array, higher frequencies narrowband excitation pul...
