Abstract
�� are the normalized polarization vectors receiver � at the source and is two-way traveltime is the is the gradient of two-way traveltime is the ray amplitude. The describes where� and� the contrast source radiation pattern at the image point. The combination of sources and receivers will dictate �� and� matrix� data � the maximum possible coverage �� in migration dip and hence the is also data dependent. The complete image is constructed by an additional stack over scattering angle and azimuth. support� The ‘measure’ in equation (1) � is modified by introducing the conical in migration dip and the
