This paper focuses on data processing for an active forward-looking sonar (FLS). Digital sonars, in general, are concerned that are transmitting different waveforms on the elements of a uniform linear array. The FLS enables row data processing that extracts target locations used for navigation safety purposes on large ships and vessels. The FLS images represent overlapping areas that can be combined to one image. Numerous different techniques have been developed for the object classification and interpretation of those images. However, many image processing algorithms consider images simply as a collection of points and do not associate them with physical sensors.
