中文摘要:
      水声信号检测是被动声呐系统进行目标探测所需的重要支撑技术,信号检测的性能直接影响到被动声呐系统对目标探测的能力.对被动声呐信号检测技术的研究情况进行了梳理,将其归纳为基于时域信息的信号检测技术和基于空域信息的信号检测技术两大类.在分析现有技术不足和应用需求的基础上,指出弱信号、低虚警率和有效利用水声传播信息等是被动声呐信号检测技术可能的发展方向.
英文摘要:
      Underwater signal detection is the important supporting technology for passive sonar system to monitor targets, and the performance of signal detection directly affects the target detection capability of passive sonar system. This paper sort out the main techniques and achievements of passive sonar signal detection, which could be classified into two categories: the temporal information based signal detection technique and the spatial information based signal detection technique. Through the analyses of the existing problems and the application requirements, the potential developing direction of passive sonar signal detection is pointed out, that is, weak signal detection, false alarm probability reduction, and effective use of underwater acoustic propagation information in signal detection.
