PREMIGRATION DEGHOSTING FOR MARINE STREAMER DATA USING A BOOTSTRAP APPROACH IN TAU-P DOMAIN.

摘要

Methods and systems for optimized receiver-based ghost filter generation are described. The optimized ghost filter self-determines its parameters based on an iterative calculation of recorded data transformed from a time-space domain to a Tau-P domain. An initial ghost filter prediction is made based on generating mirror data from the recorded data and using a least squares technique during a premigration stage.
