wiki里面写得很清楚。
torpedo条目里:
Though Lupis' original design had been rope guided, torpedoes were not wire-guided until the 1960s. During the Second World War, the U.S. experimented with frequency hopping radio controlled torpedoes using matching pairs of punched card rolls based on those of player pianos.
Hedy Lamarr条目里:
Together, Antheil and Lamarr submitted the idea of a secret communication system in June 1941. On August 11, 1942, U.S. Patent 2,292,387 was granted to Antheil and "Hedy Kiesler Markey", Lamarr's married name at the time. This early version of frequency hopping used a piano roll to change between 88 frequencies and was intended to make radio-guided torpedoes harder for enemies to detect or jam.
很清楚,实验是40年代开始的。最后成功是60年代。专利文献清清楚楚,Hedy Lamarr是第一发明人。
