Research on the Backscattering Problem of Acoustic Wave Movement Disturbance
In this paper ,the backscattering problem of acoustic moving obstacles in time domain with Dirichlet boundary conditions is studied. First solve the time domain wave equation ,collect dynamic acoustic near-field data for moving ob-stacles in a limited observation time ,and then establish a problem of the neural network model ,the time domain of the near field data as the input sequence ,the shape of known shape as the output sequence ,solve the backscattering problem. Finally for different movement speed ,effectively reverse the position and trajectory of moving obstacles. Numerical experiments show the effectiveness of the proposed method.
