SharpSeis - Deghosting/Broadband Processing Software

In typical marine seismic acquisition, a streamer towed on a given depth records not only an upgoing wavefield reflected from the subsurface, but also a downgoing field reflected from the sea surface and known as ghost wavefield. Destructive interference of the upgoing and the ghost wavefields creates a set of notch frequencies in the recorded spectrum, which results in limiting frequency band and decreasing resolution.
