  Topic      :       Algorithm of Iterative Linearized Inversion for Wave Equation

　

  Abstract    :

  In practice, a valuable problem is to obtain subsurface information from

  multiply backscattered wave data. In this talk, we use a simple wave

  equation to discuss this inversion problem. Our approach is the traditional

  one. But, we deduce a derivative matrix and consider an iterative linearized

  algorithm to modify subsurface structure such that calculated scattered signal

  of the subsurface structure gives the best fit to the measure data.
