Yes indeed, it is therefore distinguished from Radar which uses radio-wave emissions, hence Radio Detection( or direction) and ranging. Sonar is used on ships- though some Blimps used it in sonic rangefinders used in pin-pointing altitude and also to detect submarines. The German made device was called an Echolot ( Echo- Location plot) by the Germans and Sonicaltimeter by the USN boys. The idea was championed by Admiral Rosenthal, who saw it as an easy transition to use of Blimps in an anti-sub role. the British referred to SONAR as Asdic- Anti-Submarine Detection improvement committee, who developed the device. Porpoises, some whales, and it is understood seals ( Pinnipeds, not commandos!) use naturally existent Sonar, as Bats employ radar.

Can sonar be used out of water?
sonar can not be used outside water it is used under water to transmit sound waves through ultrasonic pulses
Do sonar produces ultrasound waves to map and locate objects underwater?
Active sonar ping is audible, so is not ultrasonic. Passive sonar just listens, but it takes time to determine objects bearing, speed & direction of travel. There is ultrasonic sonar for short range detection such as mines and frogman.
Ultrasonic waves transmitted into and received from the test material in the form of repetitive bursts of acoustic energy what is this called?
You could mean Sonar which is the detection of objects underwater
What Types of waves are used in echolocation?
As the name suggests, sonar uses sonic waves (sound). Typically, sonars use sounds with frequencies inaudible to human ear.Another answer:Actually, sonar uses a wide range of frequencies. Very low frequencies (100 Hz to 1 kHz) are used for long range detection and deep sea floor sounding. Midrange frequences (1 kHz to 10 kHz) are used for target identification. Ultrasonic frequencies (50 kHz and up) are used in navigation and commercial sonar devices like fish finders.
How can you trace ultrasonic waves?
What?! Trace ultrasonic waves? Are you one hundred per cent cuckoo?! Why would anyone trace ultrasonic waves these days??
Which kinds of sound waves can be produced by bats?
Bats produce high frequency (also known as ultrasonic) sound waves, which they use as a type of sonar, to locate insects in the air.
Can sonar be used out of water?
sonar can not be used outside water it is used under water to transmit sound waves through ultrasonic pulses

What is sonar in a scientific definition?
SONAR stands for SOund Navigation And Ranging.SONAR is a device that uses ultrasonic waves to measure the distance , direction and speed of underwater objects.
Form of sonar used to detect and locate enemy submarines by means of ultrasonic waves?
Type your answer here... ASDIC
How do dolphins hear underwater?
they use SONAR. :)
What are ultrasonic sensors also known as?
Ultrasonic sensors are also known as transceivers but are more generally called transducers. Ultrasonic sensors work similar to radar or sonar which generate high frequency sound waves.
What do ultrasonic sensors do?
They are similar to radar or sonar. They evaluate attributes of a target by interpreting the echoes from radio or sound waves respectively.
Ultrasonic abilities of dolphins?
Sonar
Form of sonar used to locate enemy submarines by ultrasonic waves?
Due to their short ranges, ultrasonic (>20khz) frequencies aren't used for ship or submarines' primary Active Sonar systems. Though the actual frequencies used are classified, I can say that they're nowhere near the ultrasonic range. Submarines do employ ultrasonic frequency detection systems that are passive sonar based, but they're primarily for detecting active sonar from homing torpedoes. They're also annoying for detecting any bottle-nosed dolphins in the area when you're at Periscope Depth.
How do Airplanes use Sonar waves?
they don't
What exactly are ultrasonic sensors used for?
They use sonic waves to detect things. They are used to sense volume of liquid in a tank as well as in humidifiers, sonar, medial ultrasonography, burgular alarms and non-desctructive testing.
