声纳信号预处理的窄带信号提取技术研究

吊放声纳设备在协同作战时,为了避免协同设备间的相互干扰,同型号的两台设备需要工作在不同的频带,每台设备的工作频带有比较严格的要求,而这种要求用常规的有源滤波器或无源LC滤波器都很难实现设计要求,文章提出了一种新的窄带信号获取技术。

Research on the Extraction Technology of Narrowband Sonar Signal

Dipping sonar equipment in cooperative combat,in order to avoid the mutual interference between collaborative equipment,with models of two sets of equipment needed to work in different frequency bands.Active filter and passive LC filter are difficult to meet the requirements,this paper presents a new narrow-band signal acquisition technique.
