Richardon提出了回聲定位方案(英國專利)。vin and Russian scientist Constantin Chilowsky. They called their device the 39。. The transducer of the hydrophone consisted of a mosaic of thin quartz crystals glued between two steel plates with a resonant frequency of 150 KHz. Between 1915 and 1918 the hydrophone was further improved in classified research activities and was deployed extensively in the surveillance of German Uboats and submarines. The first known sinking of a submarine detected by hydrophone occurred in the Atlantic during World War I in April,1916. 水聲學發(fā)展歷史 ? 1925年, 研制出用于船舶導航水聲設備 —— 回聲測深儀。
