(Radio Detection and Ranging) is basically a means of gathering information about
distant objects by transmitting electromagnetic waves at them and analyzing the
echoes. Radar has been employed on the ground, in air, on the sea and in space.
Radar finds a number of applications such as in airport traffic control, military
purposes, coastal navigation, meteorology and mapping etc.
development of the radar technology took place during the World War II in which
it was used for detecting the approaching aircraft and then later for many other
purposes which finally led to the development of advanced military radars being
used these days. Military radars have a highly specialized design to be highly
mobile and easily transportable, by air as well as ground.
Military radar should be an early warning, altering along with weapon control
functions. It is specially designed to be highly mobile and should be such that
it can be deployed within minutes.
radar minimizes mutual interference of tasks of both air defenders and friendly
air space users. This will result in an increased effectiveness of the combined
combat operations. The command and control capabilities of the radar in combination
with an effective ground based air defence provide maximum operational effectiveness
with a safe, efficient and flexible use of the air space. The increased operational
effectiveness is obtained by combining the advantages of centralized air defence
management with decentralized air defence control.
FEATURES AND BENEFITS
Typical military radar has the following advanced
features and benefits: -
day and night capability.
¢ Multiple target handling and engagement capability.
¢ Short and fast reaction time between target detection and ready to fire
¢ Easy to operate and hence low manning requirements and stress
reduction under severe conditions.
¢ Highly mobile system, to be used
in all kind of terrain
¢ Flexible weapon integration, and unlimited number
of single air defence weapons can be provided with target data.
resolution, which gives excellent target discrimination and accurate tracking.
The identification of the targets as friend
or hostile is supported by IFF, which is an integral part of the system.
the short time when the targets are exposed accurate data must be obtained. A
high antenna rotational speed assures early target detection and a high data update
rate required for track accuracy.
radar can use linear (horizontal) polarization in clear weather. During rains,
to improve the suppression of rain clutter, provision exists to change to circular
polarization at the touch of the button from the display console.
