MILITARY RADARS
[attachment=25165]
RADAR (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. The 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.
In this paper we will discuss about the advanced features and
benefits of military radar, system configuration of a typical
military radar, operating the radar, system functions, various
terminal equipments used along with their functions and some of
the important parts of the radar such as transmitter, receiver,
antenna, AFC (Automatic Frequency Control) etc.
MILITARY RADARS
INTRODUCTION
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.
Military 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.
ADVANCED FEATURES AND BENEFITS
Typical military radar has the following advanced features and benefits: -
All-weather day and night capability.
Multiple target handling and engagement capability.
Short and fast reaction time between target detection and ready to fire moment.
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.
High 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.
During 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.

The 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.
THE SYSTEM CONFIGURATION
A typical military radar system can be split up into three parts:
1) Radargroup
The radargroup consists of antenna, mast unit, remote control, high tension unit, LO/AFC
(Local Oscillator/Automatic Frequency Control) unit, radar transmitter, radar receiver,
video processor, waveguide drier and IFF interrogator.
The transmitter and receiver forms the active part of the system. The integrated radar/IFF
antenna is fitted on the collapsible mast, mounted on the container. The container is
connected by cable to the operator/control shelter.
