Abstract :
This paper considers the imaging of objects located close to rough surfaces such as ocean or terrain. If transmitters and receivers are also located close to rough surfaces, incident wave is no longer a plane wave, nor a spherical wave in free space and it is necessary to consider Green´s functions with the point source located close to the surface, similar to the Sommerfeld dipole problem.
