RADAR is an acronym of ra(dio) d(etection) a(nd) r(anging) which was coined by Lieutenant-Commander Samuel M. Tucker and Lieutenant-Commander F. R. Furth of the United States Navy in November 1940. The verb is probably derived from the noun.

Acronym of radio detection and ranging. Coined by the United States Navy in 1940. The lowercase form (radar) is by anacronymic evolution.
