專業(yè)釋義

機(jī)械工程

• 被動(dòng)聲吶

  Along with the decreasing noise radiation of underwater vessels, it appears a big challenge to the passive sonar.
  隨著艦船噪聲的降低，對被動(dòng)聲吶的檢測性能提出了巨大的挑戰(zhàn)。

  交通運(yùn)輸工程

• 被動(dòng)聲納

  Therefore, passive SONAR, aiming at universal noise targets, becomes the dominating SONAR of submarine. As we know, noise target ranging technology is one of its main problems.
  因此,被動(dòng)聲納就成爲(wèi)了潛艇的主戰(zhàn)聲納,針對更具普遍意義的噪聲目標(biāo),噪聲目標(biāo)測距技術(shù)是其中的重要研究課題。

  電子、通信與自動(dòng)控制技術(shù)

• 被動(dòng)聲納

  Submarine noise is the main interference of passive sonar system, which decreases the SNR at the input of the passive sonar, resulting in the deduction of sonar ranging.
  潛艇自噪聲是被動(dòng)聲納系統(tǒng)的主要乾擾。 它使聲納接收耑的輸入信噪比降低,導(dǎo)致被動(dòng)聲納的有傚作用距離相應(yīng)減小。
