Abstract: Described herein are architectures, platforms, computing systems, and methods for mitigating noise in wavefield extrapolation and imaging. In one aspect, a method of wavefield extrapolation is provided that includes receiving data representing at least one measurement of pressure wavefield or particle motion wavefield; modeling the received data as a sum of signal and noise; providing a noise model to components of the received data; and weighting the measured components of the received data to reduce the impact of noise of results of the wavefield extrapolation.
