水聲定位系統(tǒng)使用水下聲標(biāo)測定艦船或其他目標(biāo)相對位置的海上定位技術(shù)和方法。目前，在水下進(jìn)行定位和導(dǎo)航比較常見的方法就是聲學(xué)方法。聲學(xué)定位技術(shù)是利用水聲設(shè)備對已知目標(biāo)在一個特定的時間和空間中進(jìn)行定位的技術(shù)，即確定目標(biāo)(如船只)的方位和距離。自從1912年在美國出現(xiàn)了第1臺水聲測深儀以后，開始有了水聲助航設(shè)備。二戰(zhàn)中，對水下目標(biāo)的探測和測量受到了重視，并在戰(zhàn)后得到了迅速的發(fā)展。1958年，美國華盛頓大學(xué)應(yīng)用物理實驗室在達(dá)波灣建成了三維坐標(biāo)定位跟*水下武器靶場。這種水下定位定位跟*技術(shù)在六十年代后期得到廣泛應(yīng)用，成為魚雷靶場的主要測試方法。迄今為止，國內(nèi)外水下武器靶場使用的水下定位定位跟*系統(tǒng)有多種類型，按其安裝方式可分為固定式定位跟*系統(tǒng)、活動式(船載)定位跟*系統(tǒng)和輕便式定位跟*系統(tǒng)。淺水多波束裝備生產(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(jìn)行粗淺的定位，對于艇身較大的潛艇來說比較有利，因為測量的基線較長，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(yuǎn)遠(yuǎn)的拖在潛艇的后面進(jìn)行探測，拖曳聲吶的使用大幅強(qiáng)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，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(biāo)。水下聲學(xué)測速裝備生產(chǎn)公司。貴州水下機(jī)器人聲吶儀器</p><p

迄今為止，水下目標(biāo)定位定位跟*的主要手段仍是依賴于幾何原理的水聲學(xué)定位方法。通常用聲基線的距離或激發(fā)的聲學(xué)單元的距離來對聲學(xué)定位系統(tǒng)進(jìn)行分類。水聲定位系統(tǒng)，根據(jù)所實施的原理和測量手段不同，又可分為“方位--方位”、“方位--距離”和“距離--距離”三種測量系統(tǒng)。大部分的長基線、短基線系統(tǒng)都屬于后者。距離測量水聲定位系統(tǒng)是通過測量水下聲源所輻射的聲信號從發(fā)射到接收所經(jīng)歷的時間及聲速來確定聲源到各接收點的距離，從而實現(xiàn)對目標(biāo)進(jìn)行定位的。云南水下小目標(biāo)識別儀器</p><p
