发明名称 ESTIMATION OF DIRECT ARRIVAL SIGNALS BASED ON PREDICTED DIRECT ARRIVAL SIGNALS AND MEASUREMENTS
摘要 Estimation of direct arrival signals based on predicted direct arrival signals and measurements can include obtaining notional source signatures for notional sources that correspond to source elements in a seismic source. A first predicted direct arrival signal at a first location and a second predicted direct arrival signal at a second location can be determined. The first location corresponds to a seismic receiver and the second location does not correspond to a seismic receiver. A transfer function can be determined based on the first predicted direct arrival signal at the first location and the second predicted direct arrival signal at the second location. An estimated direct arrival signal at the second location can be determined based on the transfer function and a measurement by the seismic receiver corresponding to the first location. The estimated direct arrival signal represents what a measured direct arrival signal would be at the second location.

主权项 1. A method, comprising: obtaining notional source signatures for notional sources that correspond to source elements in a seismic source; determining, by a machine, using the notional source signatures, a first predicted direct arrival signal at a first location and a second predicted direct arrival signal at a second location, wherein the first location corresponds to a seismic receiver, and wherein the second location does not correspond to a seismic receiver; determining, by the machine, a transfer function based on the first predicted direct arrival signal at the first location and the second predicted direct arrival signal at the second location; and determining, by the machine, an estimated direct arrival signal at the second location based on the transfer function and a measurement by the seismic receiver corresponding to the first location, wherein the estimated direct arrival signal represents what a measured direct arrival signal would be at the second location.
