Abstract :
The wavelet transform, as an important tool of signal processing, has been applied to many fields. In this paper, a fast wavelet transform (FWT) algorithm and a source location algorithm based on the FWT are presented. Based on these algorithms, a health monitoring system for anisotropic material structures was developed. The algorithms can improve the precision and speed of source location. The health monitoring system can locate the impact damage and identify the impact load history with a good precision in real-time.
