声跟踪 meaning in English

acoustic tracking

Utts is an underwater acoustic tracking system which may operate either synchronously and asynchronously . its main task is to track and locate multiple underwater maneuvering targets accurately
水下目标跟踪系统是一个同步与异步工作方式兼容的水声跟踪定位系统，主要任务是精确跟踪和定位多个水下运动目标。
Area electronic buoys system is a large - scale underwater sound equipment of tracking and locating moving objects such as submarines , torpedoes and ships . with advanced vector sensors as detective devices , it has excellent antinoise performance , and its signal noise ratio is high
区域电子浮标系统是一套大型的水声跟踪定位设备，其主要任务是准确跟踪和定位海上多个运动目标(如潜艇、鱼雷、船只等)的运动轨迹。
Active underwater acoustic positioning / tracking systems locate target by measuring the range from object to receiving sensors . usually the target - receiver range can be got by the propagating time of a signal pulse . if this propagating time is larger than the pulse repetition period , it will mean that more than one signal pulse are on propagation
主动水声跟踪定位系统通过测量脉冲信号的传播时延可以测得目标相对接收机的距离，当此传播时延大于系统同步周期时，时延测量就会呈现不确定性，可能相差若干个重复周期，导致定位解多值，称之距离模糊现象。
