水聲通信水下通信非常困難，主要是由于通道的多徑效應(yīng)、時(shí)變效應(yīng)、可用頻寬窄、信號(hào)衰減嚴(yán)重，特別是在長距離傳輸中。水下通信相比有線通信來說速率非常低，因?yàn)樗峦ㄐ挪捎玫氖锹暡ǘ菬o線電波。常見的水聲通信方法是采用擴(kuò)頻通信技術(shù)，如CDMA等。補(bǔ)充：水聲通信技術(shù)發(fā)展的已經(jīng)較為成熟，國外很多機(jī)構(gòu)都已研制出水聲通信Modem，通信方式主要有：OFDM，擴(kuò)頻以及其它的一些調(diào)制方式。此外，水聲通信技術(shù)已發(fā)展到網(wǎng)絡(luò)化的階段，將無線電中的網(wǎng)絡(luò)技術(shù)（AdHoc）應(yīng)用到水聲通信網(wǎng)絡(luò)中，可以在海洋里實(shí)現(xiàn)多方位、立體化通信（可以與AUV、UUV等無人設(shè)備結(jié)合使用），但只有少數(shù)國家試驗(yàn)成功。水下搜索裝備生產(chǎn)公司。貴州水下聲學(xué)測(cè)速設(shè)備</p><p

聲吶結(jié)構(gòu)安裝：傳統(tǒng)上潛艇安裝聲吶的主要位置是在前端的位置，由于現(xiàn)代潛艇非常依賴被動(dòng)聲吶的探測(cè)效果，巨大的收音裝置不只是讓潛艇的直徑水漲船高，原先在這個(gè)位置上的魚雷*也得乖乖讓出位置而退到兩旁去。其他安裝在潛艇上的聲吶型態(tài)還包括安裝在艇身其他位置的被動(dòng)聲吶聽音裝置，利用不同位置收到的同一訊號(hào)，經(jīng)過電腦處理和運(yùn)算之后，就可以迅速的進(jìn)行粗淺的定位，對(duì)于艇身較大的潛艇來說比較有利，因?yàn)闇y(cè)量的基線較長，準(zhǔn)確度較高。另外一種聲吶稱為“拖曳聲吶”，因?yàn)檫@種聲吶裝置在使用時(shí)，以纜線與潛艇連接，聲吶的本體則遠(yuǎn)遠(yuǎn)的拖在潛艇的后面進(jìn)行探測(cè)，拖曳聲吶的使用大幅強(qiáng)化潛艇對(duì)于各方位與不同深度的偵測(cè)能力，尤其是潛艇的尾端。這是因?yàn)闈撏У奈捕送瑫r(shí)也是動(dòng)力輸出的部分，由于水流的聲音的干擾，位于前方的聲吶無法聽到這個(gè)區(qū)域的訊號(hào)而形成一個(gè)盲區(qū)。使用拖曳聲吶之后就能夠消除這個(gè)盲區(qū)，找出躲在這個(gè)區(qū)域的目標(biāo)。四川水下立體監(jiān)控裝備</p><p
