語源
英語の原文（Wiktionary）
The noun is derived from RADAR by anacronymic evolution. 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.
