Sonar (which stands for SOund NAvigation and Ranging) can be made to identify the object it pings on - if active sonar; if passive sonar, identify the object making the sound it picks up. The higher the frequency of the active sonar ping, the better the resolution - but the shorter the range. At higher resolutions, it is not hard for the sonar to identify the object it pings on. At lower frequencies, the range is greater but it is harder for the sonar to identify what is being pinged. Another benefit of active sonar is the range and direction of the target can be discerned. Passive sonar just listens to the ambient water. Identification of the sound source can be made if the frequencies of the target making the sound are known and identified in a database. One problem with passive sonar is that it is hard to know the range of the target making the sound, although the direction will be known. Water temperature and depth have a great effect on sonar, so this must be taken into account when calculating distance. Sonar is used in the Military, Geological Surveying, and the Medical field.

How SONAR is made?
Depends on what type of sonar as in the technology used by navy to identify under sea contacts then: A sonar is a method of detection most commonly used by the navy. It works by emitting a sound into the water of which goes down and when it hits something it bounces off that object and will return to the emitter of which is timing the time between the creation of the sound and the receiving of it. This time is the easiest way of identifying the depth of the object. In there simplest form they are a speaker a microphone and a electronic timer oh and some water. 1) Release a sound into the water whilst starting the timer which is rigged to turn off when the microphone receives the sound. 2) wait for the sound to bounce off an object or the sound to hit the bottom of the object holding the water. 3) as soon as the microphone receives the sound the timer will shut down and you will know the distance of the object after you convert the time to distance.
What is the benefit of sonar?
It helps find things underwater. Whales and dolphins use sonar to locate food and obstacles. Sonar is a useful tool in warfare: it can be used to locate and avoid obstacles. Sonar technology has allowed for safer sea travel. The assurance of safe travel attracts more travellers, thus bringing more income into the sea travel business. Sea travel is and was a driving force in the process of globalisation (this is basically the interconnectedness of the world), so, in summary, an impact/benefit of sonar on the world is that it was one of the driving forces of globalisation.
Which remote sensing technologies uses sound?
SONAR
How is multibeam sonar technology used?
Multibeam sonar technology is a offshore surveying tool used by hydrographic surveyors in navigational charting. It is primarily used in the fields of geology and oceanography.
What is an Underwater detection device called?
Sonar SOund Navigation And Ranging
What do Scientsts use sonar for?
Scientsts use sonar to map the depth of water in sea and river etc..,they also use sonar to locate and identify object underwater
Why does a bat use sonar?
A bat uses "sonar" because of it's lack of sight. A bat's "sonar" is the closest thing it has to sight, as it can identify individual objects with it.
How do sonar devices send out sound waves?
They use a machine
Why is it not possible to use sonar to determine the speed of an object travelling faster than the speed of sound?
Sonar uses sound waves to measure distances by calculating the time it takes for the sound waves to bounce back. However, when an object is traveling faster than the speed of sound, the sound waves emitted by the sonar system cannot catch up with the object to bounce back, making it impossible to accurately determine the speed of the object using sonar.
What were the two different types of sonar?
The two types of sonar are active and passive.Active sonar uses a transmitter, a device that converts electrical energy to sound energy, to send out sound waves. The sound waves travel through the water until they strike an object. The object reflects them in various directions. Some of the reflected waves return to the sonar, where they strike a receiver. Sonar determines distances by measuring the time taken for a sound wave to travel from the transmitter, reflect from the object, and travel to the receiver.Passive sonar receives sound waves given off by some other source, but does not transmit sounds. Passive sonar can therefore determine the direction of an object, but is not as effective as active sonar in determining its distance.Hope I cleared your doubt!- Harman Kahlon
How does sonar work using sound energy?
Sonar works by emitting sound waves from a transducer into the water. These sound waves travel through the water until they encounter an object, at which point they bounce back to the sonar device. By measuring the time it takes for the sound waves to return, the sonar device can calculate the distance to the object.
How does a camera use Sonar?
A camera uses sonar to detect the distance to the object you are taking a picture of so it can focus the lens properly.
On what princple does sonar and radar works?
A sonar transmits sound waves and captures it back after they strike an object. They work on the dopplers principle.
How is sonar range detected?
Sonar uses sound waves to detect objects underwater by bouncing off them and measuring the time it takes for the waves to return. The distance to an object is then calculated based on the time it takes for the sound waves to travel to the object and back to the sonar device. This process allows sonar to estimate the range to objects in the water.
How do bats create sounds?
Bats create sound based on location, like sonar. when they travel they emit sonar like waves to identify objects. Echolocation
The device used for locating submerged object under sea is?
sonar
Antonym for sonar?
Sonar is a method of sound based ranging. Therefore as an object it is not subject to an antonym. There is the principal of radar which can also range, but it uses radio waves instead.
