Linearized 3D acoustic equation for LSRTM-style modeling with a background velocity model vp and a reflectivity model mp.

Models

• vp: background velocity
• mp: reflectivity / perturbation model

Receiver Field

• sh1: scattered pressure-like wavefield

Backends

• eager PyTorch
• CUDA propagator backend
