【摘要】 被动声纳对非合作脉冲的检测一直是研究的热点与难点,本文将小波变换应用于传统脉冲信号截获检测系统,提高了带内信噪比,并且在实现非合作脉冲检测的同时获取了声源方位信息,提升了被动声纳用于未知脉冲信号检测效果。更多还原

【Abstract】 The detection of non-cooperative pulse by passive sonar has always been a hot spot and difficult point in the research. In this paper, the wavelet transform is applied to the conventional pulse signal interintercept detection system to improve the signal-to-noise ratio, detect non-cooperative pulse and obtain the direction of sound source, and improve the detection effect of passive sonar for unknown pulse signal.更多还原
