hi, Shiv mpr(radar) being inducted on Friday is it Indian made or Imported from Israel. please clarify lots speculation's going around.
its Israeli radar coverage upto 300km
Israel doesn't master AESA tech, they own it all from USA!
Cheap systems are waste of time and money
Albeit much debated but an excellent and potent weapon system.
is army going to induct it

Stealth aircraft achieves 94% radar invisibility
NASHIK, December 31: The Defence Research and Development Organisation (DRDO) and the Indian Air Force (IAF) jointly experimenting with the development of a Stealth aircraft, have achieved 94 per cent of radar invisibility.According to Squadron Leader K P Gawd (from 7 Base Repair Dept, Air Force Station, Tughlakabad), who presented a paper on "Steps towards fabrication of an invisible aircraft" at the 13th National Convention of Aerospace Engineers held at the Hindustan Aeronautics Ltd (HAL) complex at Ojhar, a breakthrough had been achieved during experiments involving two scale models of an aircraft. According to Squadron Leader Gewd, Time Domain and Frequency Domain methods were used in addition to the two antenna method to determine radar invisibility and a 94 per cent invisibility was achieved. Efforts are being made to reduce the Radar Cross Section (RCS) signature of the aircraft to reduce detection by an enemy radar. The process is to coat an object with radar absorbing materials, which absorb energy from electromagnetic fields passing through them. Such materials have complex indices of refraction, which include magnetic and electric effects. There are two kinds of such materials-narrow band absorbers and broad bad absorbers. Besides, body shaping, impedance leading and chiroshield play a crucial role in fabricating an invisible aircraft. The DRDO and the IAF used an absorber having electromagnetic properties in KU band, following the two antenna method (spectrum Analyser) the time domain method and the frequency domain method. The drawbacks experienced were the RCS isolation error and the frequency response error. The former was caused by leakage between the antenna while the latter by non ideal frequency response of the cables, connectors, couplers and antennas. The errors were subsequently rectified and zero reflection for all frequencies achieved.
The development of an invisible aircraft is being done on the lines of the B 2 Stealth Bomber of the United States Air Force. Experts believe thatit is possible to make retroreflectors such as ship and submarines invisible to sonars.

Can barak missiles counter Harpoons??
"Israel doesn't master AESA tech, they own it all from USA!"….
Thats simply not true. Look on the Elta 2075/2052…
btw what I heared the Indians was astonished+amazed by the 2075. They have now a perfect AEW&C platform.
Will RF seeker technologies be transfered to India ?
"Can barak missiles counter Harpoons??"
its primarily a counter for harpoon and against chinese supersonic antiship missiles specfically sea skimmiers
If this missile can not defend within its range, then none else can.
Rubbish…Guys, remember the war at the Lebanon Border. Hezbollah hit an Israeli frigate with a home made unguided rocket!
This frigate was equipped with the latest Barak system…Imagine if a Harpoon coming!
We have been played by Israel again…
@anon 3:35. Is this the AMCA or the UCAV that they are testing? Or just an independent TD? In either way, its a great news that IAF and DRDO are seriously working on indigenous Stealth Aircrafts. 94% invisibility. Is this better than comparable aircrafts?Can someone clarify?
[email protected]:32, rubbish. The Israeli ship was hit by a chinese made missile, and the ship did not have its barak system active to conserve operational life. It was a human error.
[email protected]:56 MPR is from LRDE.
There is no doubt Israeli corvette Hanit was indeed hit by an iranian built, Chinese designed C-602 or a C-705. What is not well known is that the Barak system was turned off. Worse still, their lunch break was explosively interrupted by this missile!
So, it is not a failure of Barak.
