Poststack Migration Lab




Figure 1. Poststack data and associated migration image on the bottom. There are 6 point scatterers embedded in the homogeneous velocity model.

Objective: Execute program post.m to reproduce above figure. The data are produced by ray tracing and the migration is by diffraction-stack migration.

Procedure:

  1. Download the following programs: post.m, ricker.m, migrate1.m, model1.m, plotit.m, xcorr1.m.
  2. Type post.m to generate the above picture for a single scatterer model. The animation displays the partial migration image as the code sequentially migrates each trace, one after another.
