Introduction
Sometimes, when conditions are right, you can hear you own echo. If you shout
"Hello," the sound may bounce back at you from a large object. You then hear
your own voice coming back. Your returning voice is called an echo. Radar and
sonar are electronic devices that use the principle of an echo to detect and locate
objects.
Both radar and sonar locate objects from the echo of a signal that is bounced off
the object. Radar uses radio waves, which are a type of electromagnetic energy.
Sonar uses the echo principle by sending out sound waves underwater or
through the human body to locate objects. Sound waves are a type of acoustic
energy. Because of the different type of energy used in radar and sonar, each
has its own applications.
Radar
The word "Radar" was formed from the first letters of the term "Radio detection
and ranging." a radio wave is a type of electromagnetic radiation. (microwaves,
x-rays, and light waves are other types.) it is the fundamental part of this form
of technology. "Detection," as used here, means finding an object or target by
sending out a radio signal that will bounce back off the target as a radio echo.
"Ranging" means measuring the distance to the target from the radar set (the
device that sends out the radio signal and picks up the returning echo).
A true radar system uses radio waves. Another system, called optical radar or
lidar (from the first letters of the term "Light detection and ranging"), is based
on the same principle as radar but uses light waves.

Applications of Radar
Radar has many various fields of application as it listed below
 Military
 Remote Sensing
 Air Traffic Control
 Law Enforcement and Highway Security
 Aircraft Safety and Navigation
 Ship Safety
 Space
 Other Applications

5. 4
Military
Important part of air defence system,operation of offensive missiles & other
weapons
Target detection, target tracking & weapon control
Tracks the targets, directs the weapon to an intercept and assess the
effectiveness of engagement
Also used in area, ground & air surveillance.

6. 5
Remote Sensing
Weather observation TV. Reporting
Planetary observation
Below ground probing
Mapping of sea ice
Air Traffic Control
Used to safely control air traffic in the vicinity of the airports and enroute
Ground vehicular traffic & aircraft taxing
Mapping of regions of rain in the vicinity of airports & weather

7. 6
Law Enforcement & Highway Safety
Radar speed meters are used by police for enforcing speed limits
It is used for warning of pending collision, actuating air bag or warning of
obstruction or people behind a vehicle or in the side blind zone

8. 7
Aircraft Safety & Navigation
Airborne weather avoidance radar outlines the regions of precipitation &
dangerous wind shear
Low flying military aircrafts rely on terrain avoidance & terrain following
radars to avoid collision with high terrain & obstructions
Ship Safety
Radar is found on ships & boats for collision avoidance & to observe navigation
buoys, when the visibility is poor
Shore based radars are used for surveillance of harbours & river traffic

9. 8
Space
Space vehicles have used radar for clocking & for landing on the moon
Used for planetary exploration
Ground based radars are used for detection & tracking of satellites & other
space objects
Used for radio astronomy as shown in the figure below
Other Applications
It is used for non-contact measurement of speed & distance
Used for oil & gas exploration
Used to study movements of insects & birds
Ground Penetrating Radar Applications
 Shallow GPR surveys
Locate pipes and utilities
Buried objects
Cemeterly & grave location
 Deep gpr surveys
Landfill & trench delineation
Bedrock depth studies
Sink hole location

10. 9
Hand-Held Radar Applications
Security & border surveillance system
Underground, through-wall & ocean imaging
Automotive safety, including collision-avoidance & intelligent cruise-control system
“smart” device such as lights, heaters & tools that automatically turn on or off
Medical diagnostics
