给出了它们的修正值，详细讨论了该方位角在±90°和±180°附近变化时的具体情况，并给出了声纳基阵姿态补偿模型的算法和步骤。

This discovery might help explain how all whales hear,researchers say.the work might also might also help scientists understand how animals are affected by underwater sonar the cuvier's beaked whales dive deep into the ocean in search of food.

研究人员称，这项发现很可能有助于解释所有鲸类的听觉问题，这项研究还可能帮助科学家进一步理解动物怎样在水下接收到声纳信号。

Combined with depth gauge, magnetic compass and control computer, the vehicle can be controlled to navigate in a certain direction and at certain depth.

This is a kind of sonar - an echo-location system.

这是一种声纳装置，一种回声定位系统。

This kind of emulator is widely used in sonar system research, production, routine, and personnel train.

该模拟器在声纳系统研制、生产、使用维护和人员培训等方面具有广泛的用途。

At approximately 05.30 on Saturday 24 May, as the German squadron was about to leave the Denmark Strait, Prinz Eugen's hydrophones detected the presence of two additional ships some distance to port.

5月24日，星期六，早5点30分，当德国舰队正要离开丹麦海峡的时候，"欧根亲王"上的声纳系统探测到有另外两艘舰船在他们的左翼。

The ultra-sonic fence is a "time barrier" that when activated exposes the present time.

那个超声纳墙是一个时间屏障，当它被激活时就能暴露在现在时间内。

Acceleration sensitivity, which determines the noise level of sensing array induced by cable dithering and towing instability, as a result of the special working scheme, circumstance and structure installation of the towed linear array, is a key parameter of the fiber optic hydrophone for the towed linear array application. Therefore, the reduction of FOH acceleration sensitivity is important for the towed linear hydrophone array to achieve an excellent performance.

拖曳线列阵的工作方式、环境条件和结构安装等特点对光纤水听器的性能提出了许多特殊的要求，特别是加速度灵敏度，它关系到拖曳线列阵声纳能否有效地抑制由拖缆抖动及拖曳力变化等引起的振动噪声的干扰，因此降低拖曳线列阵用光纤水听器加速度灵敏度是光纤水听器拖曳线列阵系统性能的重要保障。
