• 被動聲納

  Passive sonar system detects and judges the target which is based on radiate noise of the target. Line spectrum detection is distinguishing line spectrum of the radiate noise from broad band noise, and detects the sonar target accurately.
  被動聲納是根據(jù)目標航行時發(fā)出的輻射噪聲來檢測目標并判別目標類型的，被動聲納的線譜檢測就是要將艦船輻射噪聲的線譜分量從寬帶背景噪聲中提取出來，以實現(xiàn)對聲納目標的正確檢測。
