Report Description
RADAR is an acronym derived from radio detection and ranging is electronic equipment for
detecting and tracking objects. Radar uses radio waves to determine the direction, range,
altitude or speed of an object. It is used in detection of spacecraft, ships, aircraft, missile and
vehicles. RADAR uses radio energy for ranging and detection of an object. They are widely used
in weather forecasting, meteorology and geology purposes. Initially RADAR was developed for
military and defense purposes. However, with technological advancement such as greater
receiver sensitivity and high power output it can also be used in several other applications such
as tracking missiles and detecting aircrafts
In RADAR, short bursts of radio energy are transmitted and reflected from the target as an echo.
The radar signals are generated by the transmitter and received by a sensitive receiver.
Directional antennas are used in RADAR for the purpose of transmitting the pulse and receiving
the echo. The frequency range used by RADAR is divided into two groups. The first group
includes X-band with a frequency range of 9,300 MHz to 9,500 MHz. The second group is S-band
having frequency range of 2,900 MHz to 3,100 MHZ. Different techniques used in ranging and
detection include bi-static, mono-static and quasi-mono-static. In bi-static technique, the
transmitter and receiver antenna are located at different locations whereas in mono-static both
the antennas are co-located for target. In quasi monostatic the transmitter and receiver
antennas are slightly separated but appear as co-located.
