Indian Radar Systems

 Rohini Radar:
The Central Acquisition Radar (3D-CAR) is a 3D radar developed by DRDO
for use with Akash SAM. The 3D CAR was developed as part of a program
between DRDO and Poland’s PIT to develop a family of mobile, S-Band 3D
radars.

The areas of cooperation were in developing the Planar Array and general
architecture. The Indian variant is the 3D CAR, a medium range
surveillance radar for Akash at Group level, intended to provide high
mobility and comprehensive high and low level coverage. The Polish
versions, are the TRS series of S Band mobile radars such as the TRS-17
and TRS-19. The original Indian (3D CAR) and Polish (TRS 17) radars
shared the basic architecture and antenna but differed in terms of
purpose designed transmitter/receivers, and signal processing equipment.
The TRS series for instance can track 120 targets, while the Indian
radar tracks 150.

Rajendra Radar:
The Rajendra Multi-Function Phased Array radar system, designed at the
Electronics and Radar Development Establishment (LRDE), part of DRDO, is
currently in production at Bharat Electronics Limited. This is named
after India’s First president Dr. Rajendra Prasad.


The LRDE is working on the Rajendra III radar for the Indian Army.[1]
Rajendra III is a slewable phased array radar based on the T-72 chassis.
As of 2007, the BLR-III vehicle on T-72 chasis was ready for a track
test. The Phased array antenna is fabricated at Bharat Electronics
Limited (BEL), Ghaziabad. Collimated beam pattern and s/s cure for all
16 spot frequencies has been taken.

Current orders for the Rajendra and its derivatives are at least 32
units, considering the order for 2 Squadrons of the Akash system by the
Indian Air force and the indent for 28 Weapon Locating Radars by the
Indian Army.

 
INDRA Radar:

The Indian Doppler Radar (INDRA) series of 2D radars were developed by
India’s DRDO for the Army and Air Force. The INDRA-I is a is a mobile
surveillance radar for low level target detection while the INDRA-II is
for ground controlled interception of targets.

INDRA-I is a 2D mobile surveillance radar for low level target
detection. The radar is housed in two wheeled vehicles. Some of the main
features are automated Track While Scan (TWS), integrated IFF and high
scan rate for high speed target detection. The radar is produced by
Bharat Electronics Limited and inducted into service. The INDRA-I was a
landmark project for the DRDO, as it was the first large radar system
designed by the organization and produced in number for the defence
forces. The Indian Air Force operates thirty INDRA-I’s whereas the
Indian Army also has several.




INDRA-II

It is a variant of INDRA radar for ground controlled interception of
targets. The radar uses pulse compression for detection of low flying
aircraft in heavy ground clutter with high range resolution and ECCM
capabilities. The radar has been produced by Bharat Electronics Limited
and is used by Indian Air Force and Army. Seven INDRA-IIs have been
ordered by the Indian Air Force.

 

Aerostat Radar:
India has recently acquired Aerostat radars. The entire system is
divided in major parts. Firstly, the aerostat balloon which has been
acquired from Israel and second part is the payload on board the balloon
which consists, advanced programmable radar (APR), Electronic
Intelligence (ELINT), Communication Intelligence (COMINT) and V/UHF
radio telephony equipment and Identification Friend or Foe (IFF). It has
the capability to be integrated with AWACS and ground air defence
environment and funtion as a command and control centre. Depending upon
the payload the theethered balloon can be raised to the height between
10000 feet to 16000 feet.


The system gives a seamless radar cover of 300 km plus at low level
along with good RT range and requisite ELINT. The system could be termed
as static AWACS. Off course it comes with some vulnerabilities and
limitations, like weather, wind speeds, lightning & thunder, launch
& recovery periods are vulnerabilities. Its virtues also make it a
prime target for enemy therfore it needs to be protected by exclusive
air defence weapons. But we hope that the advantages of such system
would outlast the limitations.

GreenPine Radar:
India had acquired and deployed two Green Pine radars around July 2002
and another one in August 2005.[33] The Swordfish Long Range Tracking
Radar of the Indian Defence Research and Development Organisation is an
acknowledged derivative of the original Green Pine.[34]


The Indian government has sought to purchase the complete Arrow system
since 1999,[3] but in early 2002 the U.S. vetoed Israel’s request to
sell the Arrow 2 missiles to India,[4][33] exercising its right as a
major funding contributor.[35] U.S. officials argued that the sale would
violate the Missile Technology Control Regime.

Swordfish is an Indian Long range tracking radar specifically developed
to counter ballistic missile threat. It will be a part of India’s
ballistic missile program. First testing of this radar was in March
2009. Main aim of the test was to validate the capabilities of the
indigenously developed Swordfish Long Range Tracking Radar (LRTR). “The
missile to be hit will be fired from a longer distance than it was in
the earlier test. DRDO tested whether the radar could track the incoming
missile from that distance or not” said a member of the project.

Swordfish Radar:


Swordfish is an acknowledged derivative of the Israeli Green Pine long
range radar, which is the critical component of that country’s Arrow
missile defence system. [1] However, it differs from the Israeli system
as it employs Indian Transmit Receive modules, signal processing,
computers and power supplies. It is also more powerful than the base
Green Pine system and was developed to meet India’s specific BMD needs.
Indian Army : Weapon Locating Radars:

The BEL Weapon Locating Radar (WLR) is a mobile artillery locating
Phased array radar developed by India. This counter-battery radar is
designed to detect and track incoming artillery and rocket fire to
determine the point of origin for Counter-battery fire.

The WLR has been jointly developed by DRDO’s Bangalore based laboratory,
LRDE and the Government owned Bharat Electronics Limited (BEL). The
sub-systems have been fabricated by BEL based on the DRDO designs and
delivered to LRDE for integration.

 
GS 100:

French defense avionics company Thales and Bharat Electronics Ltd (BEL)
have announced a deal for supply of 19 Ground Smarter GS-100 low level
portable radars to the Indian Air Force.

India initiated procurement of low level radar systems for the IAF in 2003.

Finalization of the contract was announced during the 2009 Dubai Air Show.

“This contract reinforces our position in the Indian region as a major
supplier of air defense radars,” said Richard Deakin, Thales senior vice
president and head of the air systems division. “BEL is a leading
supplier of defense electronics systems and subsystems and plays a
leading role in a number of major Indian defense programs.”

Under the TOT deal, Thales will build the initial six radars at its
Limours facility, southwest of Paris. BEL will build the remaining 13
radars in India.

Details of the project and GS-100 capabilities are listed at my knol Thales Ground Smarter GS-100 radars for IAF.
