Data Processing Based on Complex Continuous Wavelet Transform in Project Test

The singularity can be determined by the local modular maximum line and its Lipschitz exponent,which can be obtained through the multi-scale complex continuous wavelet decomposition.Then the incident wave,pile-toe reflection wave and flaw reflection wave can be judged by the position of singularity.The method provides a more flexible and elaborate analysis and reduces the potential-error reading from the original signal directly.An analytic example tested on the pile-top was completed in this paper. The results show that complex wavelet transform is better than real wavelet transform in judging both effective length and flaw position.
