In Lamb wave damage detection of aircraft structure, it needs to address the problem of the environmental temperature influence. In this study, a weighted time domain warping (WTDW) temperature compensation method is proposed. Without any prior parameters or models, the temperature influence on Lamb wave signal can be adaptively compensated by WTDW. Furthermore, the temperature over-compensation problem of traditional dynamic time warping (DTW) that can easily suppress the defect information in the compensated signals is addressed. Therefore, WTDW is conveniently applied to the practical Lamb wave damage detection. Firstly, based on the fundamental theoretical analysis of DTW, the adaptive temperature compensation theory of WTDW is studied. Then, associated with the linearly-dispersive signal construction ( LDSC) dispersion compensation damage imaging algorithm, the WTDWbased high reliability and high resolution damage imaging method under environmental temperature variances is proposed. Experimental results on an aluminum plate ( 800 mm × 650 mm × 2 mm) show that the proposed WTDW method can adaptively compensate the influences that the environmental temperature changes from the room temperature (23℃ ) to -20℃ ~ 50℃ . And the damage location error of the WTDW-based Lamb wave high reliability imaging is less than 2. 8 mm.
