Preconditioned Conjugate Gradient Algorithm-Based 2D Waveform Inversion for Shallow-Surface Site Characterization

Figure 6

Normalized seismograms and inversion results based on the PCG in the noise-containing test of the complex structure model. (a-b) Normalized seismograms with 20% and 50% Gaussian white noise for shot 6 from the true model. (c-d) The inversion results for the normalized seismograms with 20% and 50% Gaussian white noise.
