RECONSTRUCTIONS OF SQUARE AND CIRCLE SHAPED FLAWS BASED ON INVERSE BORN APPROXIMATION
On the basis of the intrinsical performance of the frequency domain Born approximate solution for the scattering of two dimentional elastic wave,the relation between the characteristic function and the shape factor is given by two dimentional Fourier transform. Finally,simulated identification is performed for two shapes of defects on computer.
