Application of an Automatic Noise or Signal Removal Algorithm Based on Synchrosqueezed Continuous Wavelet Transform of Passive Surface Wave Imaging: A Case Study in Sichuan, China
Passive surface wave imaging based on noise cross-correlation has been a research hotspot in recent years.However, because randomness of noise is difficult to achieve in reality, prominent noise sources will inevitably affect the dispersion measurement.Additionally, in order to recover high-fidelity surface waves, the time series input during cross
