Two wavefields can be retrieved from the measured reflection response at the surface. One is the Green's function at a chosen virtual receiver depth level in a layered model generated by a source at the surface. The other wavefield consists of the upgoing and downgoing parts of a wavefield that focuses at the virtual receiver depth level. From the upgoing part of the focusing wavefield an image can be computed at one-way vertical travel time and with correct amplitudes of the local reflectiondoi:10.1109/eucap.2014.6902553 fatcat:7hdm5cgvunah7eccjzvhhw5qkm
