What are the uses of RADAR and sonar?

RADAR uses radio waves for detection purposes and SONAR uses ultrasonic waves to detect and locate underwater objects and their distances. Both have their application in the defence and military.

What are some uses of sonar?

Sonar is also used in acoustic homing torpedoes, in acoustic mines, and in mine detection. Nonmilitary uses of sonar include fish finding, depth sounding, mapping of the sea bottom, Doppler navigation, and acoustic locating for divers.

What are 2 things that use sonar?

Whales, dolphins, and bats use echolocation, a natural type of sonar, in order to identify and locate their prey. These animals emit “clicks,” sounds that are reflected back when they hit an object.

What are the uses of radar?

Radars today are used to detect and track aircraft, spacecraft, and ships at sea as well as insects and birds in the atmosphere; measure the speed of automobiles; map the surface of the earth from space; and measure properties of the atmosphere and oceans.

When was radar first used?

1935
It is historically correct that, on June 17, 1935, radio-based detection and ranging was first demonstrated in Britain. Watson Watt, Wilkins, and Bowen are generally credited with initiating what would later be called radar in this nation.

How was the radar used in ww2?

Radar, which is essentially “seeing” with radio waves, found dozens of other uses in the war. It was used to aim searchlights, then to aim anti-aircraft guns. It was put on ships, where it was used to navigate at night and through fog, to locate enemy ships and aircraft, and to direct gunfire.

What is the difference between a radar and a sonar?

First, let’s understand the difference between the radar and the sonar. The radar uses radio waves (electromagnetic waves). The sonar uses sound waves (typically ultrasound waves which have frequencies above human hearing range).

What are the applications and uses of sonar?

This page covers applications or uses of SONAR. The SONAR term stands for SOund Navigation And Ranging. SONAR uses include under water research, locating sub-marines, medical field, detecting small objects etc. What is SONAR? • It is a system used for under water study. • SONAR technology is similar to radar, ultrasound and seismics technologies.

Is sonar affected by any countermeasures?

• Sonar is unaffected by any countermeasures, but it can be affected because of attenuation of sound waves by marine life. Following are the types of SONAR.

How does passive sonar detect the range of an object?

Rather, it only detects sound waves coming towards it. Passive sonar cannot measure the range of an object unless it is used in conjunction with other passive listening devices. Multiple passive sonar devices may allow for triangulation of a sound source.
