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. |
