发言人克劳普说他不知道具体细节，但是之前传闻内容涉及声纳浮标，它能够识别鲨鱼并传出警告信号。
Klopper said he was unaware of details, but past speculation has included sonar buoys able to identify sharks and transmit a warning signal.
声呐浮标测试系统能够模拟水下声信号，用以检测声呐浮标的工作状态和性能。
The sonar buoy testing system can emulate signal of underwater sound and detect the operating status and performance of sonar buoy.
为了实现水下载体高精度的定位，GPS声纳浮标需解决两个方面的技术难点：高精度的系统时钟同步和定位信号的高精度时延估计。
As for the high precision positioning of underwater targets, the GPS sonobuoy technique has two bottlenecks: high precision system clock synchronization and high accuracy time delay estimation.
一旦探测器发出音频信号，潜水员就用软木浮标作上标记，待稍后进行挖掘。
Whenever the audio tone of the detector sounded, a diver would mark the spot with a white cork float and return later to excavate it.
分析了浮标在风、流、浪作用下的漂浮状态和受力规律，查明了浮标使用过程中存在被海水淹没、信号灯发出的灯光信号难于被发现、浮标缆断缆等问题的成因。
The floatage state and Load rule of the buoy is analyzed. The causes are found of the buoy submersing in seawater, the alarm light signal ghosting and the buoy cable breaking off.
