Write a modified Kirchoff migration program (constant velocity) to focus surface wave scatterers in the
frequency range from 5 to 20 Hz—do not assume any depth dependence to the surface wave scatterers.
Test the program using discrete point scatterers. Assume that you have corrected the
surface waves for geometric spreading

Discuss the following:
1)How could you modify your Kirchoff migration code to focus surface wave scatterers from
different depths in the subsurface?
2)How would you modify your code to handle multiple scattering (i.e. scattering from scatterers)?


Can somebody give me some hints??? Thank you so much for you guys help!
