What is "datar"

DATAR, short for Digital Automated Tracking and Resolving, was a pioneering computerized battlefield information system. DATAR combined the data from all of the sensors in a naval task force into a single "overall view" that was then transmitted back to all of the ships and displayed on plan-position indicators similar to radar displays. Commanders could then see information from everywhere, not just their own ship's sensors.

Development on DATAR was started by the Royal Canadian Navy in partnership with Ferranti Canada (later known as Ferranti-Packard) in 1949. The system proved too costly for the post-war Navy to develop alone, and when the Royal Navy and the United States Navy declined to share in the program it was ended. Both would then go on to start development of similar systems to fill this same role, the RN's Comprehensive Display System and the USN's Naval Tactical Data System.

DATAR is a computerized battlefield information system.
