Linearly dispersive signal construction of Lamb waves with measured relative wavenumber curves

•LDSC is presented for Lamb wave dispersion compensation in unknown structures.•LDSC can be performed with theoretical wavenumber curves or measured relative ones.•A narrowband spectroscopy method is proposed for relative wavenunmber measurement.•A LDSC-based high resolution Lamb wave imaging method...
