Comparative analysis of formulations for crossed artifact elimination in the frequency–Bessel spectrograms

The frequency–Bessel transformation method has significantly advanced the extraction of multimodal surface waves in seismic research. However, the presence of crossed artifacts in frequency–Bessel spectrograms, particularly when stations are regularly distributed, presents a persistent challenge. Va...
