聲吶結構安裝：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聲吶的探測效果，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聲吶聽音裝置，利用不同位置收到的同一訊號，經(jīng)過電腦處理和運算之后，就可以迅速的進行粗淺的定位，對于艇身較大的潛艇來說比較有利，云南水下避障儀器，因為測量的基線較長，準確度較高。另外一種聲吶稱為“拖曳聲吶”，因為這種聲吶裝置在使用時，以纜線與潛艇連接，聲吶的本體則遠遠的拖在潛艇的后面進行探測，云南水下避障儀器，拖曳聲吶的使用大幅強化潛艇對于各方位與不同深度的偵測能力，尤其是潛艇的尾端。這是因為潛艇的尾端同時也是動力輸出的部分，由于水流的聲音的干擾，云南水下避障儀器，位于前方的聲吶無法聽到這個區(qū)域的訊號而形成一個盲區(qū)。使用拖曳聲吶之后就能夠消除這個盲區(qū)，找出躲在這個區(qū)域的目標。核電水下安防裝備生產(chǎn)公司。云南水下避障儀器</p><div

水聲定位系統(tǒng)使用水下聲標測定艦船或其他目標相對位置的海上定位技術和方法。通常所說的水聲定位系統(tǒng)所測得的目標位置結合起來進行坐標變換，就能得到水下目標在大地幾何坐標中的位置或軌跡。坐標，都是相對于某一參照物的位置而言。這個參照物有時就是基陣的載體(通常相對坐標系的某一個軸線和艦船的艏艉線重合)，它并不真正給出目標的大地幾何坐標位置。然而水聲定位系統(tǒng)和其他的導航系統(tǒng)(如近年來獲得廣泛應用的衛(wèi)星導航定位系統(tǒng))結合起來進行坐標變換，就能得到水下目標在大地幾何坐標中的位置或軌跡。云南水下聲學測速儀器標準水聽器裝備生產(chǎn)公司。</p><div

水下導航定位——地球物理屬性導航：對于大多數(shù)水下潛器的使用要求來說，采用聲學導航顯然是不可能的，而且是不切實際的。如果我們事先能得到精確的環(huán)境測繪圖，就可以通過對地球物理參數(shù)(如深度測量法、磁場、重力異常）的測量，來對水下航行器在地球上的位置進行估計。這些方法主要是基于被測量參數(shù)在空間分布上有足夠變化的前提下，通過與先驗的環(huán)境測繪圖進行匹配，來實現(xiàn)導航的一種方法。這就是地球物理屬性導航，是自然界的生物，如鳥、魚和其他動物遷移時普遍采用的導航方式。地球物理屬性導航又可分為基于地磁導航、基于重力場導航和地形輔助導航。 </p><p> 由于電磁波在水中衰減的速率非常的高，無法做為偵測的訊號來源，因此以聲波探測水面下的人造物體成為運用更好的手段。無論是潛艇或者是水面船只，都利用這項技術的衍生系統(tǒng)，探測水底下的物體，或者是以其作為導航的依據(jù)。作遠距離傳輸?shù)哪芰啃问?。于是探測水下目標的技術——聲吶技術便應運而生。聲吶是各國海軍進行水下監(jiān)視使用的主要技術，用于對水下目標進行探測、分類、定位和跟*；進行水下通信和導航，保障艦艇和反潛飛機的戰(zhàn)術機動和水中武器的使用。此外，聲吶技術還各方面用于魚雷制導、水雷引信，以及魚群探測、海洋石油勘探、船舶導航、水下作業(yè)、水文測量和海底地質地貌的勘測等。和許多科學技術的發(fā)展一樣，社會的需要和科技的進步促進了聲吶技術的發(fā)展。俄羅斯海軍專門將一艘核子K-403號潛艇改成聲吶測試用艇，可見其重視程度。多波束聲吶裝備生產(chǎn)公司。</p><div

水下導航定位，慣性導航：慣性導航是一種自主式的導航方法。它完全依靠機載設備自主的完成導航任務，和外界不發(fā)生任何光、電聯(lián)系，因此隱蔽性好，工作不受氣候條件的限制。這一獨特的優(yōu)點，對作為軍*目的而應用的各種航行器特別重要。所以近幾十年來，慣性導航在導彈、艦船、潛艇、水下武器、飛機、宇宙航行器上都得到了寬泛的應用，在導航技術中占有突出的地位。慣性導航用于水下導航，是通過將加速度對時間兩次積分來獲得水下潛器的位置，其優(yōu)點是自主性和隱蔽性好。缺點是由于陀螺隨時間不斷漂移，在長時間工作情況下導航定位累積誤差較大。早期的慣導系統(tǒng)復雜、體積大、能耗高不適合潛水器使用，現(xiàn)在隨著光纖、激光等新型固態(tài)陀螺技術的不斷進步，為實現(xiàn)研制體積小、精度高、可靠性好、能耗與成本指標低的INS提供了條件，因此在未來的自主式潛航器（AUV)上將有可能大量采用這些新型INS。目前，國外水下潛器常用的INS主要有:美國霍尼韋爾公司RL34環(huán)形激光陀螺慣性導航系統(tǒng)、美國Crossbow公司的微機械陀螺慣性導航系統(tǒng)等。前視聲吶裝備生產(chǎn)公司。四川水下導航設備</p><p

聲吶結構分類：被動聲吶。聲吶設計者只能對某預定目標的聲音進行設計，如目標為潛艇，那么目標自身發(fā)出的噪聲包括螺旋槳轉動噪聲、艇體與水流摩擦產(chǎn)生的動水噪聲，以及各種發(fā)動機的機械振動引起的輻射噪聲等。因此被動聲吶（噪音站）與主動聲吶比較根本的區(qū)別在于它在本艦噪聲背景下接收遠場目標發(fā)出的噪聲。此時，目標噪聲作為信號，且經(jīng)遠距傳播后變得十分微弱。由此可知，被動聲吶往往工作于低信噪比情況下，因而需要采用比主動聲吶更多的信號處理措施。被動聲吶沒有發(fā)射機部分?；匾粽尽y深儀、通信儀、探雷器等等均可歸入主動聲吶類，而噪音站、偵察儀等則歸人被動聲吶類。云南水下避障儀器</p><p
