IDN TAKE: Should India have Followed the Chinese & Pakistani Weapons Development Model

[Royal Kathiyawadi]

The old proverb is, ''if you can't beat them, then join them''....
The Indian concept is....''if you can't beat them, then accuse them''.
The losers should remember that defence sector is no call centre community where Sunita swaps her Saree with a Skirt and apes Sandra.

aylast they work in call centers (with idiotic accents) but u Pakistanis main work in west is toilet cleaning and suicide bombing innocent people

FORCE Magazine/Tempur defence writer Prasun K Sengupta wrote in a few days ago to say, "Before DRDO and BEL take us all to Cloud 9 regarding the Rohini and Revathi 3-D radars, Rohini and Revathi 3-D radars are derivatives of the Polish TRS-19 radar, developed by Poland's Przemyslowly Instytut Telekomunikacji SA. What the DRDO has done in fact is buy all the IPRs and manufacturing licences from the two Polish companies. I had written about this way back in late 2006."

I quote from the article Prasun's referes to from FORCE Magazine in late 2006, titled "Flights of Fire":

By late 2001 the DRDO had inked a comprehensive technologytransfer-cum-design rights buyout package with Radwar and PIT under which the DRDO would obtain and transfer the production technology for the PIT-developed TRS-17 S-band, 3-D radar with 240kmrange, and Radwar-developed N-22 Sband, 2-D 100km-range gapfiller radar, their respective antennae hoisting mechanisms, microwave line-of-sight signals relay antennae and related command-andcontrol consoles to the MoD-owned Bharat Electronics Ltd (BEL) who in turn would call them the Central Acquisition Radar (CAR) and the Battery Surveillance Radar (BSR).

While the CAR would be used along with a Group Control Centre for tracking up to 120 targets and providing fire-direction for up to three Batteries (each comprising four launchers, with each launcher carrying three missiles) of the Akash MSAM, the BSR and its Battery Control Centre will be able to track 72 airborne targets and will be linked to the BEL-built Rajendra target engagement radar, whose main antenna array will comprise 2,000 ferrite phase shifters and will be able to track 64 targets out to 60km, and engage four airborne targets simultaneously with 12 missiles. For the Army and Air Force variants of the Trishul SHORADS, the DRDO opted for Radwar’s S-band, 40kmrange 3-D mobile multi-beam search radar as the principal tactical early warning sensor.

Armed with these technology-transfer deals, the DRDO had by 2003 reinvigorated the Akash’s R&D phase and on 7 December 2005 conducted Akash’s 50th test-firing which, according to DRDL Director Dr Prahlada, was the first test-firing conducted with a fully functional Battery-level command, control and communications system.

Now don't want to discuss whether it is true or not, but thing is that there is no harm in doing such thing i.e buying IPR rights from the CAR nation like Ukraine is some how done by Chinese to achieve a lot.

Prasun Sen Gupta called Prasun Chor Gupta for a reason.
You should avoid him for your intellect sake.

Hi Shiv,

Prasun has been barking up the wrong tree for a long while and his claims are an absolute farce.

PIT didnt provide any technology "buy out" for LRDE to avail of.

The LRDE actually ran a phased array project called Project Vajra, ask any of us at LRDE for details, and that led to the CAR project.

DRDO was aware of PITs radar work and asked if they were interested in taking project Vajra further. The aim was to now take the phased array project and make a Planar array radar with a brand new array that would be lighter. PIT showed their own work in this regard and agreed, they had been tapped by the Polish Govt to develop a new series of radars as well.

The joint effort of both organizations was the the 3D CAR for DRDO, and the TRS-19 for Poland.

Both radars are different, and use different signal processing units.

The item common to both radars is the basic design of the planar array antenna, which scans (electronically) in elevation, and rotates for azimuth coverage.

PIT has not developed the TRS-19 further, but have concentrated on other derivatives for long range theater coverage.

PIT also ran a tender for its own separate maritime surveillance project, and purchased LRDE's antennas (slotted array) for the same.

In India, DRDO developed the 3D CAR into the Rohini. For this radar, Astra Microwave and DRDO developed new microwave components and L&T was roped in for a new rotational assembly, for the radar to make it sufficiently compact for IAF usage. The signal processing and radar data processing was designed and developed by a team led by the Late Dr Radhakrishnan of LRDE, and Dr Cleetus (ex head, LRDE). The Rohini and Revathi are completely DRDO's babies, they in fact, dont even use the original planar array developed with PIT, but a brand new one able to handle increased power, as well as an all new digital beamformer.

The Revathi in fact, is even more sophisticated. It uses a completely de novo bi axis stabilisation system again developed by the DRDO in specific for the Navy. This is because the Revathi is intended for the Navy, and needs to be stabilised.

Reading some of the responses above, and your uncritical acceptance of the bilge that Prasun writes, is saddening.

For one, give credit where credit is due.

The Rohini is an all Indian radar developed by the DRDO, with extensive time consuming involvement by the Indian Air Force, the user. It is no off the shelf import, knocked together as license assembly under fancy terms of import of technology or technology buyout.

For more details about the DRDO's radar technology, please do look at the DRDO techfocus about the same.

Prasun is habitually unreliable when it comes to talking about the DRDO or for that matter about most matters relating to Indian defence.

Case in point, please ask him for any corroborative proof about the absolute nonsense he wrote about India corroborating with Taiwan for ramjet based missiles, and for all the hoopla about India making all sorts of fancy weapons. In his latest article, he went so far as to call the BEL WLR an active phased array radar. The man does not even know the difference between a PESA and an AESA, the former of which the Rajendra based WLR is!

Each of his articles is actually different in "Facts" from the other, merely inventing stuff on the fly to impress a not too critical audience.

Most defence professionals have long got used to these incredibly jingoistic and nonsensical claims from Tempur. Unfortunately, Force continues to carry them without due investigation.

Brother Sorry If I bother you, My intention is not to promote prasun sen theory, but the idea is to tell that that there is no harm in doing that. i.e buying the IPR

Which is false & Prasun Sen Gupta's gibberish.
Many example would be perfect but not this, like Sword Fish LR Radar (Derived from Israel's Green Pine with Indian TRM)
