由于電磁波在水中衰減的速率非常的高，無(wú)法做為偵測(cè)的訊號(hào)來(lái)源，因此以聲波探測(cè)水面下的人造物體成為運(yùn)用更好的手段。無(wú)論是潛艇或者是水面船只，都利用這項(xiàng)技術(shù)的衍生系統(tǒng)，探測(cè)水底下的物體，或者是以其作為導(dǎo)航的依據(jù)。作遠(yuǎn)距離傳輸?shù)哪芰啃问健Ｓ谑翘綔y(cè)水下目標(biāo)的技術(shù)——聲吶技術(shù)便應(yīng)運(yùn)而生。聲吶是各國(guó)海軍進(jìn)行水下監(jiān)視使用的主要技術(shù)，用于對(duì)水下目標(biāo)進(jìn)行探測(cè)、分類、定位和跟*；進(jìn)行水下通信和導(dǎo)航，保障艦艇和反潛飛機(jī)的戰(zhàn)術(shù)機(jī)動(dòng)和水中武器的使用。此外，聲吶技術(shù)還各方面用于魚雷制導(dǎo)、水雷引信，以及魚群探測(cè)、海洋石油勘探、船舶導(dǎo)航、水下作業(yè)、水文測(cè)量和海底地質(zhì)地貌的勘測(cè)等。和許多科學(xué)技術(shù)的發(fā)展一樣，社會(huì)的需要和科技的進(jìn)步促進(jìn)了聲吶技術(shù)的發(fā)展。俄羅斯海軍專門將一艘核子K-403號(hào)潛艇改成聲吶測(cè)試用艇，可見(jiàn)其重視程度。水下電話裝備生產(chǎn)公司。四川水下搜索設(shè)備</p><p
