Direct Image Reconstruction of Anomalies in a Plane Via Physical optics Far Field Inverse Scattering

摘要

It is shown how to process backscattered acoustic data to directly generate the image of an anomaly in a plane, such as an anticline, a syncline or fault. The result is based on e physical optics far field inverse scattering (POFFIS) identity. This identity states that a phase and range normalized scattering amplitude is proportional to a function which is unity in the region of the anomaly and zero outside that region.
