Understanding CMP stacking hyperbola in terms of partial derivative wavefield

Common midpoint (CMP) stacking and velocity analysis are fundamental seismi c imaging concepts based on a layered velocity model. We relate these conce pts to partial derivative seismograms, which give seismic amplitude variati ons as a function of layer coordinates. The CMP stacking hyperbola can be d escribed kinematically by partial derivative seismograms, resulting in an i nteresting seismic imaging relationship.
