We will investigate several of the principles of wave propagation that form the basis of seismic imaging theory. These include Huygens’ Principle, the Born approximation, Green’s theorem, the principle of stationary phase, and others.

We will see how these principles relate to the forward and backward propagation of seismic wavefields, and how they combine with an imaging principle to produce seismic migration. The principles will be explained pictorially; we will use math as little as possible but as much as necessary.

Also, if time permits, we will investigate special topics such as resolution, least-squares migration, migration of multiples and more. The course will be highly interactive, with lots of questions and discussion items for the class. The course material has been substantially revised since last year’s Doodletrain.
