Diffracted wave imaging method, device and electronic apparatus

A diffracted wave imaging device, comprising:

• an acquisition module configured to acquire a pre-stack seismic wave field data of a to-be-processed area;
• an extraction module configured to extract target data of a target imaging point based on the pre-stack seismic wave field data, wherein the target imaging point is any imaging point of all the imaging points in the to-be-processed area, and the target data comprises:
• a stationary point position signal of a reflected wave and a signal of a diffracted wave event;
• a fitting module configured to fit target time sample points in the target data based on a Gaussian model and solve the fitting function to determine a distribution range of the stationary point position signal of the reflected wave in the target data, wherein the target time sample points are sampling points having same time parameter;
• a first determination module configured to determine a migration imaging data of the target imaging point based on the target data and the distribution range;
• and
• a second determination module configured to determine a diffracted wave imaging result of the to-be-processed area based on the migration imaging data of all the imaging points in the to-be-processed area.
