On the relationship between stacking process and resolution. 2; Jugo shori to bunkaino ni kansuru kiso kenkyu. 2

Abstract

With respect to concept of resolution in seismic exploration using the reflection method, detailed considerations were given on processes of forming the resolution as a result of arranging observation points at vibration transmitting and receiving points. In the discussion, numerical experiments were carried out, in which the scattering stacking process is applied in a model having one scatterer existing in homogeneous media. The experiments investigated an imaging formation process of the scatterer when arrangement of the vibration transmitting and receiving points were changed from a coarse condition to a dense condition while the number of transmitting and receiving points is being increased. Resolution is created if waveforms having finite frequencies are used as input, and the imaging is performed by utilizing the limited number of vibration receiving and transmitting points. If the concept of equi-travel plane is used under these conditions, the equi-travel planes perform negation with each other, and it was indicated that visual resolution is expressed by how good the negating effect is. It was discovered that such concept of the resolution is quite ambiguous in terms of engineerings. 2 refs., 17 figs.
