DMO/AMO in the Presence of Caustics

P266 DMO/AMO IN THE PRESENCE OF CAUSTICS ALISON MALCOLM MAARTEN V. DE HOOP and JÉRÔME LE ROUSSEAU Center for Wave Phenomena Colorado School of Mines Golden CO 80401 USA Abstract Dip MoveOut (DMO) and Azimuth MoveOut (AMO) are considered in a general framework which allows for lateral variations in the velocity model including variations which generate caustics in the wavefield. DMO and AMO are constructed through the composition of operators in a general velocity model using the scattering angle and azimuth parameterisation [4]. In this parameterisation impulse responses analogous to DMO and AMO are computed in a the gas lens
