Spectral Fusion: A Tool to Merge Low and High Frequency Datasets

“Spectral Fusion” is a new tool designed to combine different seismic datasets covering the same surveyed area, with<br>different but overlapping bandwidths resulting for instance from various source/receiver depths for marine streamer data. By<br>combining data with overlapping spectra a larger bandwidth can be recovered, with the benefit of using all of the available<br>information in the overlapping frequency domain without requiring any wave shaping or predefined filters, and therefore<br>better preserving the individual phase and amplitude character of the input data.
