【摘要】 远距离的强振源和近距离的弱振源在接收器中可能会引起相同的信号强度,从而使以检测能级阈值为主的目标区域判别方式造成误判,达不到良好的毁伤效果。利用单个三轴地震波传感器接收舰船航行时产生的水中和海底声信号对目标进行被动探测定位,与舰船产生的信号强度无关,与距离也无关,经理论分析表明:该方法能够检测出舰船的运动参数及从水雷上方通过的时间,从而确定水雷的最佳打击位置。更多还原

【Abstract】 The long-range powerful sound source and short-range weak sound source may bring the same signal strength to the receiver,so that the threshold detection system of action zone will make erroneous judgment and increase the false alarm.In this case,mines cannot well cause any damage to the ship.The problem can be solved by a new detection technique.A single triaxial seismometer can be used to receive the acoustic signals transmitted through the water and sea bed by the ship under sail to detect and localize the ship.The detection method has no relation to the range as well as intensity of acoustic signal generated by the ship.The ship′s moving parameters can be estimated by the detection arithmetic to determine the best firing time.更多还原
