| But I've listened to some of these anti-sub sonars and they have a similar effect to the sound of a killer whale. |
|
| The system has two sonars fitted in a small pod-shaped submersible vessel which is towed by the ship. |
|
| Acms receives data from the sonars and other sensors and, through advanced algorithms and data handling, displays real time images on the command consoles. |
|
| Modern military submarines rely almost entirely on a suite of passive and active sonars to locate targets. |
|
| Voice communication from one submarine is transmitted by low power speakers into the water, where it is detected by passive sonars on the receiving submarine. |
