Bridge, Sonar.

Bridge, Sonar.

Lowering sonar projector.

Go ahead, Sonar.

Go ahead, Sonar.

Sonar gear manned and ready.

Sonar, Captain. Commence underwater search.

Who's on sonar, Mr Ware?

Sonar, this is the captain.

Sonar searching beam to beam, sir.

Sonar reports screwy noises from the target.

Sonar, we may have hit him hard.

The sonar system is the 4,000 metre class.

This is the dolphin's sonar. (Dolphin echolocation noises)

Sonar lash, Herr Kapitän. He has made contact.

So how would you design a perfect sonar ping?

He was the sonar engineer working for the Navy.

So that was the sonar ping they were using a down chirp.

And John went about and solved the sonar problem for the Navy.

Put sonar and radar on automobiles so they can't hit one another.

So he designed a different kind of sonar ping one that looks random.

You don't hear the surface ship anymore, you hear that pinging of a sonar.

Sonar, Captain. He's using some kind of a decoy. Can you pick him out of it?

We make maps of these mountain ranges with sound, with sonar, and this is one of those mountain ranges.

It is equipped with side scan sonar and a digital camera to obtain topographical data on the deep sea floor.

Well, in the 1960s, a guy by the name of John Costas was working on the Navy's extremely expensive sonar system.

41. The United States Navy currently maintains a radar and sonar calibration station and a headquarters building for its underwater tracking facility.

25. The United States Navy currently maintains a radar and sonar calibration station and a headquarters building for its underwater tracking facility.

It turns out a guy who was trying to develop the world's perfect sonar ping solved the problem of writing pattern free music.

For example, in oceanography, a lexicon of dolphin language is actually being created by basically visualizing the sonar beams that the dolphins emit.

If you've got an iPhone you've got sonar on there it's that same pinging that goes down to the bottom and comes back up.

So, recall that in sonar, you have a ship that sends out some sound in the water, and it listens for it an echo.

At present, the United States Navy maintains a radar and sonar calibration station on St. Croix and an underwater tracking station off its west coast.

An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar or other detection systems, like infrared (IR) or lasers.

The existence of such a ridge was confirmed by sonar in 1925 and was found to extend around the Cape of Good Hope into the Indian Ocean by the German Meteor expedition.

26. The WCRP Working Group on Sea Ice has proposed a network of about 25 upward looking sonar buoys (ULS) around the continent to provide overall estimates of the Antarctic ice thickness distributions.

The mesopelagic zone contains communities of animals that undergo daily migrations (which are visible with sonar as dense reflective layers) towards the surface at dusk to feed, returning to deeper waters at daybreak to avoid predators.

The use by ships of acoustic systems, including sonar imaging presenting local reflectivity of the bottom and thus its nature, make it possible to obtain in a precise and fast way topographic images of the relief of the seabed (bathymetry).
