Abstract
We present an original approach of true amplitude seismic imaging by means of weighted summation of multi-shot multi-offset data. In order to compute these weights one should trace Gaussian beam starting from some current point within target area towards acquisition system. The special choice of Gaussian beam provides possibility in advance to take into account geometrical spreading and illumination condition for specific acquisition system. Global Gaussian beam regularity enables one to deal with central ray field with any kind of singularities.<br>
