Dual-Driven Solver for Reconstructing the Point Sources of Elastic Wave Based on Far-Field Data

Aiming at the inverse source problem of an elastic wave, a dual-driver solver is considered to reconstruct point sources. In this way, number, location, and magnitude sources can be reconstructed from far-field measurement data. The composed data-driven module physical-driven module, which coupled by loss. loss are both driving force evolution. takes data as input, output. It trained Adam algorithm. Numerical experiments show that method effective for reconstructing multi-sources.
