Abstract:
A method for simulating a multi-shooting technique where a plurality of shots are generated simultaneously and recorded in a single shot gather, said method comprising the steps:(a) let x denote a generic point in a three dimensional medium;(b) let x.sub.s.sup.(i) denote a generic source position;(c) let F.sub.P (x,t) denote a field matrix of the wave motion at position x and time t;(d) solve the equation ##EQU9##wherein D.sub.I,P (x,t) is a block off-diagonal spatial differentiation operator matrix which is specific for each type of wave motion under consideration, wherein M.sub.I,P (x) is a medium matrix that is representative for the properties of the media in which the wave propagates, and wherein Q.sub.I (x,t) is a volume source density matrix that is representative for the action of the volume sources that generate the wavefield, wherein I and P denote the pertaining matrix elements and the summation convention for repeated subscripts applies, where n shots are generated simultaneously and recorded in a single shot gather F.sub.P (x,t), and wherein .tau..sub.i describes time delays between various shots; and(e) decoding the multi-shooting data into single shots.
