LCA to be fitted with Israeli multi-mode radar

Ravi Sharma

BANGALORE: The indigenous Light Combat Aircraft (LCA) Tejas will, after years of delay, soon be fitted with its primary mission sensor, the multi-mode radar (MMR).

P.S. Subramaniam, Programme Director, Aeronautical Development Agency (ADA), the defence laboratory that is designing the LCA, told The Hindu that “airworthy units” of the Israeli – manufactured MMR would be arriving here early next week for integration into the aircraft. The Elta designed and developed MMR, Elta EL/M-2052 which will be an interim option since India is developing an indigenous one, has already undergone tests on the flight test bed and ground rig in Israel.

One of the most crucial pieces of equipment on any fighter aircraft, the MMR determines the operational effectiveness of the machine, with no fighter aircraft being in a position to perform as one without an MMR.

In the LCA the MMR’s primary role will be to detect and locate targets, process the information, lock on the target and pass this input to the mission computer. From the mission computer this information will be utilised by the pilot as he contemplates weapon release activity. The MMR will also create ground and contour maps when selected.

The long delay in the arrival of the MMR has without doubt pushed the Rs.6,000-crore LCA programme back by many a year. Though initially ADA had intended to use the Ericsson Microwave Systems PS-05/A MMR, it was decided in the early 1990s to indigenously develop one.

But the joint efforts by Hindustan Aeronautics Limited (Hyderabad) and Electronics and Radar Development Laboratory (Bangalore) along with coordination from the Centre for Airborne Studies (CABS) failed to come up to expectations. This resulted in the ADA running weaponisation tests on the LCA with a weapon delivery pod, which is not a primary sensor, being forced to keep critical tests on hold.

MMR


Israel Aerospace Industries (IAI) has been awarded multiple orders of 34 units by India of its advanced Multi-Mission Radar (MMR) type EL/M 2084. ELTA Systems Ltd., a group and wholly owned subsidiary of IAI, is the prime contractor and developer of the EL/M 2084. ELTA's MMR addresses an emerging requirement to include all land-based radar functions in one operational unit. MMR combines a Weapon Locator Radar and an Air Defense Radar. The radar detects Surface-to-Surface medium- and short-range missiles, rockets and mortars, calculates the anticipated impact and launching points, and provides target data to air defense weapons systems. MMR is based on Active Electronically Steering Array (AESA) architecture and provides outstanding performance that was combat proven in the recent fighting in the Gaza Strip. The radar is mobile and scalable in order to meet different performance requirements. Scaling is performed by means of an antenna of varying physical size and the amount of transmit-receive (TR) module content. The current orders include 3 different versions of the radar.

 

[Arjak]

i dont have much knowledge on the radar platform to be fair ,guys
can anyone tell me which one is better, MMR or PESA??
or are they same??

 

[LETHALFORCE]

MMR is an AESA based radar for that reason it is better than PESA , but PESA is still effective.

 

[p2prada]

This is the EL/M-2084 that India may get.

MMR is any radar that can perform multiple functions at the same time. It can track air targets and ground targets at the same time. It could be PESA, AESA or lesser. It means Multi Mode Radar. As the name suggests, it has multiple modes in one unit.

 

[LETHALFORCE]

MMR takes the best scanning and multi tasking features of AESA and PESA without the cooling problems since it can work in multiple modes

The EL/M-2032 is hardly AESA. It has been in service for quite some time. The only thing particular of interest of this radar is the ease of switching modes. The Irbis-E is a PESA radar with far greater capabilities than this.

LF was talking about the EL/M 2084.
2032 is quite old. It's similar to the APG-63.

LCA will be equipped with the EL/M 2052.

2032 is the radar it has and it shares with the Sea Harriers. Is there confirmation that future tranche will have 2052?

then what is Rohini CAR is supposed to do? can any body explain difference between their functions.........as to me they both are air defence radars elbit with different capabilities

Read post 22 and post 25 mate. We were discussing about the 2084.

As for the 2052 on LCA,
IAF

Another area of concern has been the development of the MMR (multi mode radar) which is now urgently needed to support the weaponisation process. In what may be a big set back to the Bangalore-based Electronics and Radar Development Establishment (LRDE) developing the MMR, the Govt of India has announced a partnership with Israel's Elta Electronics to develop and integrate a new radar system with the airframe. To expedite the process Elta could develop their existing EL/M-2052 active electronically scanned array (AESA) radar to fill the gap. Israelis quote very advanced capabilities for this multimode radar including a multi-target tracking capability of up to 64 targets, air to ground modes include moving target display and SAR mapping, which IAF is interested in. At an AUW (all up weight) between 130 kg to 180 kg (as per antenna sizes) the EL/M-2052 should be compatible with the Tejas airframe.

Defunct Humanity: Zhuk-AE is ready for fight

Zhuk-AE is ready for fight

Russian Phasotron corporation reports Sep. 17 , that it has finished the testing program for Zhuk-AE AESA radar. The detection range for a standard aerial target is 148 km and in the perspective it will be raised to 200 km. The Phasotron's General Director Victor Tishchenko said that one of the Indian MMRCA tender request is an AESA radar with 130 km detection range. So, Zhuk-AE fulfills this request, he says.
Seemingly, Zhuk-AE is the first non-american AESA radar for fighter jets ready for use. The others still remain 'paper radars' in many aspects.

zaslon radar

zaslon radar

The Zaslon is a Pulse-Doppler radar with a passive electronically scanned array (PESA) antenna and digital signal processing. The antenna used by the Zaslon is actually a multi-channel system comprising two separate electronically controlled arrays, an X-band radar with 1700 emitters and a L-band transponder with 64 emitters brought together into a single antenna [1]. The antenna has a diameter of 1.1 meters and is fixed in position with a scanning sector of +/-70 degrees in azimuth and +70/-60 degrees in elevation [2]. The X-band components of the radar uses reciprocal ferrite phase shifters that allow the radar to position beams in around 1.2 msec [1]. This high performance is one of the big advantages of phased array radars compared with the previous generation of mechanically scanned arrays which take seconds to perform the same functions as a phased array. The detection performance of the Zaslon radar is stated to be 200 km against a target with a Radar cross section (RCS) of 19 m2, the radar can track up to 10 targets while engageing 4 of those at any one time with either R-33 radar guided or R-40, R-60 IR guided air to air missiles.

The radar was a landmark in aviation since it was the first time a PESA radar (previously found only on ground based systems) had been installed in a jet fighter. The Zaslon radar was publicly unveiled at the 1991 Paris Airshow with its associated MiG-31 interceptor, the Russians even removing the radome of the fighter to allow the Zaslon's revolutionary antenna to be seen. Also at Paris was the US F-117 Nighthawk (revolutionary for its use of stealth technology) which the Russians suggested should take to the air with the MiG-31 to see if the Zaslon could detect the F-117. Unfortunately no such contest was ever conducted though Russian experts were confident that Zaslon would have been able to detect the F-117 during flight.
The first aircraft fighter to use phased array radar was the Mikoyan MiG-31. The MiG-31M's SBI-16 Zaslon phased array radar is considered to be the world's most powerful fighter radar.

Indigenous Doppler radar replaces Chinese model

Mumbai: After the China-made Doppler radar was rejected for security reasons, the Indian Meterological Department (IMD) has decided to purchase indigenous Doppler radars. Chief minister Ashok Chavan is trying hard to get it installed before monsoon.

The Doppler radar — which reached the city three weeks ago — is manufactured by Bharat Electronics Ltd. The indigenous radar is larger than the Chinese version, though it is much cheaper. As the radar is
bigger in size, the design of the installation had to be changed. According to the officials, though the site of the installation is same, the variation in the size has delayed the process of installation. Efforts are underway to complete the installation before the monsoon.

The Chinese radar had arrived last April and its installation had begun atop Archana building in Navy Nagar, Colaba. Technical experts associated with the company manufacturing the radar were supposed to visit the site to offer their expertise. However, in view of estranged relations between India and China, security concerns were raised since Navy Nagar is a highly sensitive area.
"There was skepticism after gadgets were given as gifts to (Indian) defence officers when they were visiting their counterparts in China. Allowing (Chinese) scientists to enter the highly sensitive area of Navy Nagar was thus out of question. Finally the radar was sent back to Delhi last November," an official related to meteorological work told DNA.The indigenous radar was supposed to be installed in Kochi. But the state government lobbied hard with the prime minister's office pointing out the urgency for the radar in Mumbai. The China-made radar — which costs Rs12 crore — may be installed in some other part of the country, the official said. M Ramesh Kumar, additional chief secretary, relief and rehabilitation department, said, "The installation work is on and we are hopeful that the radar will be installed and commissioned before monsoon. Chief minister Ashok Chavan has written a letter to the central government to expedite the work."The idea of installation of the Doppler radar was first mooted after a deluge hit the city on 26th July, 2005.

Weather forecasts to get more accurate, courtesy Chinese radars

Weather forecasting in India is all set to get more accurate with the met office setting up Chinese made Doppler radars across the country that can track and predict fast- evolving weather systems such as thunderstorms, cyclones and cloudbursts.The radars, which have been procured from Beijing Metstar Radar Company, will be installed at a height of 16 metres on top of buildings."The Doppler Weather Radar (DWR) would provide short-range accurate weather prediction in a nearly 500 km radius," Indian Meteorological Department's (IMD) director Dilip Saha told IANS here.
He said: "Work is now in full swing in all the 15 locations across the country to install the radars. In some places, the installation is likely to be completed before the onset of monsoon next month."DWR has the unique capability to continuously track and predict fast- evolving weather systems such as thunderstorms, cyclones and cloudbursts.The sites chosen for installations of DWR are Delhi, Mumbai, Pune, Patna, Goa, Patiala, Mohanbari and Dibrugarh, Lucknow, Paradip, Karaikal, Kochi, Bhopal, Nagpur and Agartala."The Chinese Doppler radar will be operated round the clock. Its working speed would be very high and it will cover a wide area," Saha said."It will also be much better and more advanced than the conventional radar, which are being presently used by the IMD. The radar will pick up more accurate information about the turbulence and wind speed of the atmosphere before a cyclone or heavy shower," he said.

"And the radar will be able to predict the quantity of rainfall, and also the rainfall average during prolonged showers," he said.The cost of the each DWR equipment is approximately Rs.100 million with an additional expenditure of Rs.60 million towards development of infrastructure for setting up of the new system."Named after Austrian physicist Christian Doppler, the DWRs are expected to make a great change in the weather predictions in India," an IMD official said.Currently India has four German-made Doppler radars set up at Visakhapatnam, Machhlipatnam, Chennai and Kolkata.The installation of Chinese made DWR is part of the Rs.10-billion modernisation plan of the 135-year-old IMD."The Chinese made Doppler radar is a sophisticated instrument but cannot be said to be flawless without significant user effort over a considerable period of time," said an official of Regional Meteorology Centre (RMC) in Guwahati

Coming Soon, Cyclone-Spotting radars

India's going to be getting a little help from China in predicting the weather.Ahead of the monsoon the country's meteorological department is replacing its old conventional radars with new and advanced Chinese-made equipment that can track and predict fast-developing weather systems such as thunderstorms, cyclones and cloudbursts.The Doppler Weather Radars or DWR, which have been acquired from the Beijing-based Metstar Radar Company, will be mounted on building rooftops at a height of 16 meters and provide accurate short-range weather prediction in a 500-kilometer (310 miles) radius.

​

"The DWR is an attempt by the meteorological department to modernize its observational network," A.P. Tyagi, director general of the Indian Meterological Department based in New Delhi told India Real Time Thursday.These radars will play a vital role in providing information about bad weather events over Delhi and its adjoining areas.The 14 other locations that may soon get the new equipment are Mumbai, Pune, Patna, Goa, Patiala, Mohanbari and Dibrugarh, Lucknow, Paradip, Karaikal, Kochi, Bhopal, Nagpur and Agartala."The installation will likely be completed before the onset of the monsoon next month," Mr. Tyagi said.Named after the Austrian physicist Christian Doppler, the cost of each radar is 100 million rupees ($2 million).Currently India has five weather radars set up at Visakhapatnam, Machhlipatnam, Chennai, Kolkata and Sriharikota, according to the meteorological office.

"The Chinese radars will be operated round the clock. It will pick up more accurate information about the turbulence and wind speed of the atmosphere before a cyclone or heavy shower occurs," Mr. Tyagi said.The old equipment isn't so bad though. Authorities in the southeastern state of Andhra Pradesh have been moving tens of thousands of people from their homes since Wednesday in preparation for the arrival of Cyclone Laila today, which made landfall packing winds of 110 kilometers (70 miles) an hour. Communication and power supplies have been disrupted and even air and train services have been thrown out of gear.
