Abstract
The Kirchhoff migration method is very useful for<br>determining the position of seismic reflectors, if it is<br>known the seismic wave velocity model and the<br>traveltimes through the earth model. The traveltime<br>calculation is a necessary step for stacking the seismic<br>data by means of the Kirchhoff migration operator. In<br>this work the traveltimes are obtained by solving the<br>eiconal equation of the ray theory. A developed<br>migration algorithm is applied to synthetic models,<br>providing a very good image resolution even in the<br>presence of random noise and reflectors below domelike strucrures.
