A pulse coding and decoding strategy to perform Lamb wave inspections using simultaneously multiple actuators

•Simultaneous excitation of multiple transducers in guided wave structural health monitoring systems.•Damage imaging for spread spectrum coded pulses.•Warped cross-correlation for pulse compression and dispersion compensation. The performance of Lamb wave based monitoring systems, both in terms of d...
