A system called InTAC (instant target analysis computer) is described. InTAC enhances target analysis in two ways: it speeds up the procedure by avoiding tedious manual measurements of a sonar contact, and it can determine the position in latitude and longitude of a sonar target. This position then can be used to guide submersibles or divers to the exact location of the target for investigation or recovery purposes. This instant target analysis is performed in real time, thus avoiding costly project delays.
