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.

Can a sonar machine identify the object showing up on the sonar?
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.
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
Is a Lowrance GpS sonar made in China?
Lowrance GPS Sonar devices are not made in China. From what I could find online, it appears these devices are actually manufactured and shipped from Indonesia.
Who are 3 scientists who studied sonar?
The word sonar is an acronym for SOund Navigation And Ranging. There were some physicists that have worked on and studied the effects of sonar. The Canadian physicist Robert William Boyle, A B.Wood, and engineer Reginald Fessenden have all studied and made advancements in sonar knowledge.
