Abstract :
Wave theory is frequently used for numerical simulation of seismic wave. Different sources may be lead to different signal in the simulation. This paper utilizes staggered-grid high-order finite difference scheme to solve wave equation, and it simulates snapshots loaded respectively concentrated force, dilatational source and shear source in isotropic medium. It is necessary to help exploration researchers to interpret actual data and analyze signal types by via of numerical simulation results.
