what's the difference between sonar and radar?

Answer 1

Sonar is a sound wave.

Radar is a radio wave.

Answer 2

SONAR- Sound Navigatin And Ranging.

used in ships and submaines to dtect objects, landscapes under water.

RADAR- Radio Detection And Ranging

Radar is a system that uses electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations, and terrain. A transmitter emits radio waves, which are reflected by the target and detected by a receiver, typically in the same location as the transmitter. Although the radio signal returned is usually very weak, radio signals can easily be amplified. This enables a radar to detect objects at ranges where other emissions, such as sound or visible light, would be too weak to detect. Radar is used in many contexts, including meteorological detection of precipitation, air traffic control, police detection of speeding traffic, and by the military. The term RADAR was coined in 1941 as an acronym for Radio Detection and Ranging. This acronym of American origin replaced the previously used British abbreviation RDF (which stands for Radio Direction Finding). The term has since entered the English language as a standard word, radar, losing the capitalization in the process.

Answer 3

A sonar uses acoustic energy for ranging purposes. A radar uses electromagnetic energy.

A radar is used primarily in the atmosphere while the sonar finds usage mainly underwater.

A sonar may also be used for underwater communications.

Answer 4

Sonar is an instrument/camera used to take pictures underwater using sound. A boat tows the camera behind it. The camera is usually called a fish. It sends out the sound and measures how long it takes for the sound to come back to it, and how loud it is. A computer keeps track of the information and can makes pictures of the bottom of an ocean, lake, or river.

Radar is an instrument used to detect precipitation by measuring the strength of the electromagnetic signal reflected back. RADAR = RAdio Detection And Ranging

Answer 5

RADAR:

Radar is a system that uses electromagnetic waves to identify the range, altitude,
direction, or speed of both moving and fixed objects such as aircraft, ships, motor
vehicles, weather formations, and terrain. A transmitter emits radio waves, which are
reflected by the target and detected by a receiver, typically in the same location as
the transmitter. Although the radio signal returned is usually very weak, radio signals
can easily be amplified. This enables a radar to detect objects at ranges where other
emissions, such as sound or visible light, would be too weak to detect. Radar is used
in many contexts, including meteorological detection of precipitation, air traffic
control, police detection of speeding traffic, and by the military. The term RADAR
was coined in 1941 as an acronym for Radio Detection and Ranging........


SONAR:

Sonar is an acronym for sound navigation and ranging.It is based on the principle of echo.
It is used to find the depth of seas.Ultrazonic sound waves are sent in to water.The sound waves are reflected by the sea-bed.
the time taken for the to and fro motion is noted.

depth of sea = velocity of sound in water x time taken for the to and fro motion

Answer 6

Sonar uses sound waves (subsonic to ultrasonic). Radar uses radio waves, in the microwave band.

Answer 7

I ping only Sonar. - Submarine.

Spike on radar at the angels of 3. - Airplane. F22. Raptor. hehe..
