f Amplitude distribution along the DMO operator

The distribution of amplitudes along the DMO operator has been the subject of many papers such as Deregowski and Rocca (1981), Hale (1984), Black and Egan (1988), Bleistein (1990), and Gardner and Forel (1990). As far as we are concerned a complete solution to the problem has not been obtained. We attacked the same problem in a similary way to the approach of first referenci given above. However, there are considerable differences in terme of calculation of reflector curvature and the evaluation of integrale involved.
