Forward-Looking Sonar Ping To Ping Overlap. The data from wide-sector forward looking sonars, such as ATLAS, significant overlap from ping to ping. The ping spacing that is depicted in this figure is much larger than typical ATLAS surveys. Usually there is more than 95% overlap between successive pings.
