Directional designature without near-field hydrophone recordings
P. Scholtz, Hassan Masoomzadeh, Roy Camp · 2015
Summary Near-field recordings are commonly used for directional designature to address variations of source signatures with regards to take-off angle and azimuth. We examine two ideas for a case in which near-field recordings are not available. Decomposition of direct waves has the potential for shot-to-shot application, and a global integration of sea-bottom reflection could result in an ensemble of designature operators. Synthetic and field data examples show what can be expected from the application of these methods.
