I would like to use this thread to highlight those who claim to be journalist and often try to defame DRDO's efforts for reasons unknown.I would like members to add to this thread so that it could educate people who blindly trust journalism who keep blabbering against DRDO with ill-intentions.Please note that this link is of 2008.But i still see lot of such articles which i would like to add it to this thread and highlight it.To start with this is the link.
Article : The Truth about the Rohini radar (from Prasun K Sengupta)
This article mentioned about how Prasun K sengupta a noted defense journalist revealed the truth about DRDO buying Polish radar and claiming its own.Finally a employee of LRDE had to write comments on the efforts of DRDO and BEL.
The article starts with
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."
This argument was rebuffed by Ravi an employee of LRDE.I have highlighted his comments below.
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.
