聲吶工作原理：聲波是觀察和測(cè)量的重要手段。有趣的是，英文“sound”一詞作為名詞是“聲聲吶模式”的意思，作為動(dòng)詞就有“探測(cè)”的意思，可見聲與探測(cè)關(guān)系之緊密。在水中進(jìn)行觀察和測(cè)量，具有得天獨(dú)厚條件的只有聲波。這是由于其他探測(cè)手段的作用距離都很短，光在水中的穿透能力很有限，即使在清澈的海水中，人們也只能看到十幾米到幾十米內(nèi)的物體；電磁波在水中也衰減太快，而且波長(zhǎng)越短，損失越大，即使用大功率的低頻電磁波，也只能傳播幾十米。然而，聲波在水中傳播的衰減就小得多，在深海聲道中爆*一個(gè)幾公斤的炸*，在兩萬公里外還可以收到信號(hào)，低頻的聲波還可以穿透海底幾千米的地層，并且得到地層中的信息。在水中進(jìn)行測(cè)量和觀察，迄今還未發(fā)現(xiàn)比聲波更有效的手段。貴州水下導(dǎo)航儀器水下緝私聲吶裝備生產(chǎn)公司。</p><div

現(xiàn)代水下導(dǎo)航技術(shù)發(fā)展趨勢(shì)：隨著現(xiàn)代軍*技術(shù)的不斷發(fā)展，水下導(dǎo)航必須適應(yīng)現(xiàn)代潛艇戰(zhàn)略和戰(zhàn)術(shù)的要求，能夠?yàn)闈撏?shí)施長(zhǎng)時(shí)間隱蔽航行提供實(shí)時(shí)準(zhǔn)確的導(dǎo)航信息。潛艇導(dǎo)航技術(shù)與其他導(dǎo)航技術(shù)相比具有更為明顯的軍*特征，因此它的發(fā)展在符合導(dǎo)航系統(tǒng)發(fā)展總方向的前提下將具有自己獨(dú)特的趨勢(shì)。根據(jù)潛艇軍*行動(dòng)的要求，GPS系統(tǒng)在未來戰(zhàn)*中可能誰(shuí)都無法使用，應(yīng)注重研究和實(shí)施兩種以上導(dǎo)航體制并存的格局，為此未來水下潛艇導(dǎo)航技術(shù)將仍以慣性導(dǎo)航技術(shù)為基礎(chǔ)的導(dǎo)航技術(shù)，結(jié)臺(tái)無源重力、海底地形匹配、天文以及水聲等導(dǎo)航新技術(shù)實(shí)施潛艇綜合導(dǎo)航。

聲吶結(jié)構(gòu)分類：被動(dòng)聲吶。被動(dòng)聲吶技術(shù)是指聲吶被動(dòng)接收艦船等水中目標(biāo)產(chǎn)生的輻射噪聲和水聲設(shè)備發(fā)射的信號(hào)，以測(cè)定目標(biāo)的方位和距離。它由簡(jiǎn)單的水聽器演變而來，它收聽目標(biāo)發(fā)出的噪聲，判斷出目標(biāo)的位置和某些特性，特別適用于不能發(fā)聲暴露自己而又要探測(cè)敵艦活動(dòng)的潛艇。利用接收換能器基陣接收目標(biāo)自身發(fā)出的噪聲或信號(hào)來探測(cè)目標(biāo)的聲吶稱為被動(dòng)聲吶。由于被動(dòng)聲吶本身不發(fā)射信號(hào)，所以目標(biāo)將不會(huì)覺察聲吶的存在及其意圖。目標(biāo)發(fā)出的聲音及其特征，在聲吶設(shè)計(jì)時(shí)并不為設(shè)計(jì)者所控制，對(duì)其了解也往往不多方面。水下無線對(duì)講裝備生產(chǎn)公司。</p><div

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(zhǎng)，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)。水聲定位導(dǎo)航裝備生產(chǎn)公司。云南水下設(shè)備</p><p
