    Radar Division




NRL invented, developed, and installed the first operational U.S. radar, the XAF, on the battleship USS New York in 1938. It was rapidly transferred to industry for production. By the time of the attack on Pearl Harbor, December 7, 1941, 20 radar units were in operation. Radar of this type contributed to major Naval victories in battles at the Coral Sea, Midway, and Guadalcanal during World War II.


Areas of Research 

The Radar Division conducts research on basic physical phenomena of importance to radar and related sensors, investigates new engineering techniques applicable to radar, demonstrates the feasibility of new radar concepts and systems, performs related systems analyses and evaluation of radar, and provides special consultative services. The emphasis is on new and advanced concepts and technology in radar and related sensors that are applicable to enhancing the Navy’s ability to fulfill its mission.
