• 被动声纳

  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.
  被动声纳是根据目标航行时发出的辐射噪声来检测目标并判别目标类型的，被动声纳的线谱检测就是要将舰船辐射噪声的线谱分量从宽带背景噪声中提取出来，以实现对声纳目标的正确检测。
