摘要
舰船地震波信号是由作为"振源"的航行舰船引起的,针对舰船地震波信号含有丰富的舰船目标信息,提出了利用动圈式检波器探测舰船目标的方法。该方法利用三个单轴动圈式检波器构成三轴传感器检测舰船地震波信号,并利用三轴传感器的结构特点和方向特性对舰船目标进行被动定位。试验表明,三轴传感器能够有效检测出舰船地震波信号,对三轴传感器输出的含有目标方位信息的三分量信号进行信号处理,可以实现舰船目标的被动探测定位。
The ship＇s seismic wave field is induced by sailing ship and contains information of the target ship. Aiming at this issue, a method was proposed based on the moving-coil seismometer. By using of this method, three uniaxial moving-coil seismometers can constitute a triaxial sensor for detecting and locating the target ship by virtue of its design feature and directivity. The test confirmed that the triaxial sensor can receive the ship＇s seismic wave signal successfully by laid on the seabed. The single triaxial sensor can output the ship＇s position information that can be used for passive localization.
