Target-oriented Hessian: dimensions and structure

Since accurate imaging of reflectors is more important in the neighborhood of the reservoir, it makes sense to restrain the model space to the target area. A way to achieve this objective is to write the modeling operator ${\bf L}$ in a target-oriented fashion and explicitly compute the Hessian.
