This paper shows how to process backscattered acoustic data to directly generate the image of an anomaly in a plane such as an anticline, syncline, or fault. The result is based on a physical optics farfield 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.Subject Classification: [43]20.30, [43]20.15; [43]40.50.
