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?，云南水下通訊系統(tǒng)裝備。于是探測(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，云南水下通訊系統(tǒng)裝備。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，云南水下通訊系統(tǒng)裝備。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。水下目標(biāo)識(shí)別裝備生產(chǎn)公司。云南水下通訊系統(tǒng)裝備</p><div

海底地震監(jiān)測(cè)觀測(cè)儀器由于海水對(duì)聲波傳播的限制，利用一般的地震測(cè)量技術(shù)，人們往往無(wú)法有效地、經(jīng)濟(jì)地接收到一些重要的地震信息，如橫波及其頻散信息、三分量的地震信息等，因此產(chǎn)生了海底地震監(jiān)測(cè)這一新技術(shù)。海底地震監(jiān)測(cè)的主要儀器是海底地震儀。它的主體包括拾震器(亦稱傳感器、地震檢波器)、放大器、記錄器、石英鐘和電源等。儀器主體被密封在耐壓容器中，放置海底進(jìn)行全自動(dòng)記錄，借助浮標(biāo)和系留系統(tǒng)或自動(dòng)控制系統(tǒng)升浮而回收。海底地震儀采用可變線圈型電磁式結(jié)構(gòu)。它的體積小，比較堅(jiān)固，有良好的水密性。由于地震頻率范圍變化很大,因此要求根據(jù)不同的觀測(cè)目的,選擇短周期和長(zhǎng)周期的檢波器來(lái)分別測(cè)定適當(dāng)?shù)念l率范圍。四川水下導(dǎo)航定位裝備目標(biāo)自動(dòng)識(shí)別裝備生產(chǎn)公司。</p><div

水聲通信發(fā)展情況：這是國(guó)際上高水平的技術(shù)，在遠(yuǎn)距離水里能清楚地接收到語(yǔ)音信號(hào)，世界上也只有極少數(shù)軍使用水聲通訊的蛟龍?zhí)柺聫?qiáng)國(guó)才能做到。水聲通信機(jī)使用的是模擬信號(hào)，可是海洋中的波浪、魚類、艦船等產(chǎn)生噪聲，使海洋中的聲場(chǎng)極為混亂，聲波在海水中傳遞時(shí)產(chǎn)生“多途徑干擾信號(hào)”這一較大的難題，導(dǎo)致接收到的信號(hào)模糊不清。半個(gè)世紀(jì)以來(lái)，水聲領(lǐng)域的**對(duì)這一難題一直束手無(wú)策，老式的模擬水聲通信機(jī)一直沿用至今。由于數(shù)字通信的產(chǎn)生，陸地上的信號(hào)干擾被成功解決，水聲領(lǐng)域的**也開始了在該領(lǐng)域進(jìn)行探索。他們認(rèn)真分析了世界上抗多途干擾的幾種方法，然后課題組一致認(rèn)為還是采用電磁波抗干擾的手段——跳頻通信，它既能抗多途徑干擾又能保證信息安全。因?yàn)楹Ｋ煞趾軓?fù)雜，所以聲波傳遞時(shí)就被吸收了一部分，而且頻率越高吸收就越厲害，對(duì)于頻率低的聲波海水反而吸收少。**測(cè)得結(jié)果，聲波頻率在4000赫茲左右為遠(yuǎn)距離傳遞的較佳頻率，而用4000赫茲的頻率去實(shí)現(xiàn)跳頻通信，頻點(diǎn)與頻點(diǎn)之間的距離就很小了。
