Paper Summary
The current implementations of marine source modeling theory have been calibrated and adjusted against measured signatures with a goal of high modeling accuracy within a limited frequency band. As multicomponent streamers and source deghosting allows for utilizing a significantly broader range of frequencies in seismic imaging, adjustments to the modeling are necessary in order to achieve a better match between measured and modelled signatures over the expanded frequency band. This includes significant changes to the calibration process such as considering deghosted measurements and avoiding the historically rooted standard DFS V filtering. The modeling results after applying the improved calibration show a very good match with measured array signatures over a wide frequency range.
