Abstract
The present disclosure is directed to detecting subsurface features via a seismic survey. A system can obtain seismic data from nodes separated from each other by at least a threshold distance on a ground surface. The seismic data can include image trace data based on field trace data detected from each of the plurality of seismic data acquisition units. The system retrieves a sample interval and a parameter. The system configures a bandlimited binning function with the sampling interval and the predetermined parameter. The system applies the bandlimited binning function to a plurality of image traces of the image trace data to generate a bandlimited angle gather value for a bin in an angle gathers grid. The system generates an image based on the angle gathers grid and provides the image for display.
