After graduating with a Ph.D. in physics in 1928, he took a position at the ''Nachrichtenmittel-Versuchsanstalt'' (NVA – Navy Transmissions Laboratory) of the ''Kriegsmarine'' (Germany Navy) in Kiel. There he worked in acoustical research, specifically in ''Unterwasser-Schall'' (sonar) with the objective of improving the accuracy of detection of vessels using near-surface, underwater signals. Although his efforts led to a patent, and in 1931, he was promoted to Scientific Director of the NVA, he became convinced that the desired accuracy would only be attained by using electromagnetic, rather than acoustical, techniques.〔Rudolf Kühnhold, http://de.wikipedia.org/wiki/Rudolf_K%C3%Bchnhold〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rudolf Kühnhold」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
