Naval operations: Submarine and anti-submarine usage. in the thirties a Blimp altimeter called a Sonicaltimeter was tested on Navy Blimps by Admiral Rosenthal, noted (Blimp admiral). The device was made in Germany by Echolot- still in business. Echolot is a blend word of Echo Location or Echo-Pilot. not a Batty idea but uses in a sense ultra-sound not radar waves.
Sonar (originally an acronym for sound navigation and ranging) is a technique that uses sound propagation (usually underwater) to navigate, communicate with or detect other vessels. There are two kinds of sonar: active and passive. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used in air for robot navigation, and SODAR (an upward looking in-air sonar) is used for atmospheric investigations. The term sonar is also used for the equipment used to generate and receive the sound. The frequencies used in sonar systems vary from infrasonic to ultrasonic. The study of underwater sound is known as underwater acoustics or sometimes hydroacoustics. Source: http://en.wikipedia.org/wiki/Sonar
Sonar and radar's are used by the military, research groups, reconnaissance missions, searches for dead bodies and much more. It is a widely used technology.
Many species of sharks do not use sonar, as they have very effective senses, but some species are thought to. The hammerhead shark, in particular, is thought to use sonar waves detection.
Robotic submersibles, sonar, satellites, coring machines, and magnetometers.
Sonars were used to detect any objects that got into the detection field of the sonar. By this, the military could detect enemy submarines etc., which they couldn't see normally because of the opacity and/or darkness of the water.
SONAR is an acronym created by the navy that is the name of what they use to locate items under water. But if you wanted to, you could say the bats using echolocation on land is a type on SONAR. They basically both use sound to locate objects so they are really not very different at all.
Sonar (SOund NAvigation and Ranging) is used to find objects. Sonar is used to find ships, submarines, mines, and other objects in the Navy. Sonar is used in Medicine to find unusual tumors, organs, and cells. Sonar is used in Geology to find minerals, oil, rock formationsn, and water .
Yes sonar can be used at periscope depth. Surface ships also have sonar arrays on them. They are usually used to detect submarines.
sonar,is used to map mid-ocean ridges:]
Sonar can be used to locate large shoals of fish.
sonar is used to detect big penises
Sonar was used to detect and hunt submarines in WW2
sonar can not be used outside water it is used under water to transmit sound waves through ultrasonic pulses
1) sonar waves are used for underwater surceillance and measurements (depth) 2)visualising images in utero-ULTRASONOGRAPHY. 3)sonar is used for treatment in physiotherapy
sonar is a device used underwater for locating submerged objects and for submarine communication by means of sound waves.
Sonar is used to detect other vessels or ships/submarines through a tube-like device> Andrea
Most people do not hear the sonar signals used by animals, such as bats or dolphins.
