Virtual reflector representation theorem (acoustic medium)
The Journal of the Acoustical Society of America, 2009 The virtual reflector method simulates new seismic signals by processing traces recorded by a plurality of sources and receivers. The approach is based on the crossconvolution of the recorded signals and makes it possible to obtain the Green’s function of virtual reflected signals as if in the position of the receivers (or sources) there were a ...
