Abstract

In this paper we present a new practical and efficient method to calculate approximate seismic images without a priory knowledge of the subsurface model or velocity analysis. By analogy of the use of Feynman path integrals in waveform modeling, we develop an algorithm for model-independent imaging by summation of elementary signals over a sample of all possible paths between source and receiver. The constructive and destructive interference of these signals produces and approximate image of the subsurface.
