The backscattered acoustic signals were reconstructed into complex-valued imagery that is an estimate of the acoustic reflectivity at each position of the scene. These images were reviewed by subject-matter experts to confirm the data is free of obvious reconstruction errors. Close visual agreement between the known physical configuration of (a) the scene and (b) the SAS image confirmed that the data is free of labeling errors.
