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.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.
SONAR
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.

No, the Arctic fox does not use sonar. It is not equipped with sonar.

In the mountains i detect a rock with my SONAR.
