ESTIMATION OF A FAR FIELD SIGNATURE IN A SECOND DIRECTION FROM A FAR FIELD SIGNATURE IN A FIRST DIRECTION

摘要

The present disclosure is related to estimation of a far field signature in a second direction from a far field signature in a first direction. For a number of source elements, where the number of source elements corresponds to a seismic source, an impulse response in a first direction and a second direction can be determined. A transfer function that transforms a far field signature of the seismic source in the first direction to a far field signature of the seismic source in the second direction can be determined based on corresponding impulse responses in the first direction and the second direction. An estimated far field signature for the seismic source in the second direction can be determined based on the transfer function.

1. A method, comprising:
determining, by a machine, an impulse response in a first direction and an impulse response in a second direction of a seismic source; determining, by the machine, a transfer function that transforms a far field signature of the seismic source in the first direction to a far field signature of the seismic source in the second direction based on corresponding impulse responses in the first direction and the second direction; and determining, by the machine, an estimated far field signature for the seismic source in the second direction based on the transfer function.
