Time Domain Waveform Inversion for the Model Based on the First-Order Viscoacoustic Wave Equations

Figure 1

(a) The true model: a spherical anomaly with a of 20 is embedded in a homogeneous full space with a of 100. The red dot and the blue dot in the left figure denote the source and receiver locations, respectively. (b) The starting model has a homogeneous of 100.
