Forward-looking sonar ping-to-ping overlap. The data from wide-sector forward-looking sonars, such as ATLAS, shows significant overlap from ping to ping. The ping spacing depicted here is much larger than typical ATLAS surveys. Usually there is more than 95% overlap between successive pings. Image courtesy of Thunder Bay 2010 Expedition, NOAA-OER.
