海洋環(huán)境噪聲淺海噪聲場(chǎng)，淺海噪聲受水文條件、海底特點(diǎn)、近岸工業(yè)設(shè)施和魚(yú)類(lèi)回游的影響，隨地區(qū)和季節(jié)的變化較大。海灣和港口附近的工業(yè)設(shè)施和潮汐等噪聲源，有較強(qiáng)的晝夜和季節(jié)性的變化，因此只能粗略地繪出不同海灣、港口和附近地區(qū)的環(huán)境噪聲譜級(jí)。盡管如此，從長(zhǎng)期的大量取樣所獲得的環(huán)境噪聲平均譜，仍然是很有實(shí)用價(jià)值的。對(duì)于設(shè)計(jì)和使用聲吶設(shè)備和水下聲學(xué)儀器來(lái)說(shuō)，海洋環(huán)境噪聲是一種干擾源。必須測(cè)出不同海區(qū)和不同季節(jié)的海洋環(huán)境噪聲場(chǎng)的功率譜特征、指向性及時(shí)間與空間的相關(guān)特性，并在水聽(tīng)陣和電路設(shè)計(jì)中采取相應(yīng)措施，以提高信號(hào)噪聲比的增益。海洋生物噪聲譜是海洋生物研究和海洋捕撈的重要判據(jù)。隨著檢測(cè)和數(shù)據(jù)處理技術(shù)的進(jìn)展，對(duì)環(huán)境噪聲和接收深度的關(guān)系，噪聲場(chǎng)的方向性，冰下噪聲譜，噪聲級(jí)瞬時(shí)值的統(tǒng)計(jì)特性，及對(duì)低于10赫甚至1赫以下的噪聲源的探索等方面的研究，都有較大的進(jìn)展。</p><p> 水下定位導(dǎo)航方法：天文導(dǎo)航法。天文導(dǎo)航法是利用對(duì)自然天體的測(cè)量來(lái)確定自身位置和航向的導(dǎo)航技術(shù)。由于天體的位置是已知的，測(cè)量天體相對(duì)于導(dǎo)航用戶(hù)參考基準(zhǔn)面的高度角和方位角就可計(jì)算出用戶(hù)的位置和航向。天文導(dǎo)航系統(tǒng)不需要其他地面設(shè)備的支持，所以是自主式導(dǎo)航系統(tǒng)。不受人工或自然形成的電磁場(chǎng)的干擾，不向外輻射電磁波，隱蔽性好，定位、定向的精度比較高，定位誤差與定位時(shí)刻無(wú)關(guān)，因而得到廣泛應(yīng)用。其原理以天體作為參考點(diǎn)，可確定水下潛器的真航向。使天文導(dǎo)航潛望鏡自動(dòng)對(duì)準(zhǔn)天體方向可以測(cè)出水下潛器前進(jìn)方向（縱軸）與天體方向(即望遠(yuǎn)鏡軸線方向)之間的夾角（稱(chēng)為航向角)。由于天體在任—瞬間相對(duì)于南北子午線之間的夾角(即天體方位角）是已知的。水下救援裝備生產(chǎn)公司。</p><div

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(jiàn)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(wàn)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。深海通數(shù)字通信生產(chǎn)公司。四川水下安防設(shè)備</p><p
