Meaning , it cant be jammed.
Oh yeah , that's a ati uttam samachar .

We don’t know whether it can be jammed or not, but we know it is for taking out the jammer & radar itself.

If it takes out jammer than it cannot be jammed.
Jammer will protect itself first
Planes can be protected by flares also.
I know , I sound idiot but that's the simplest terms in which I can think about it.

Jammer is not a living thing... It's a sensor-circuitry combination following an algorithm.

So whether it can or cannot, can only depend on the functioning of the tech. Such details are not available.

Cannot vouch for how NGARM may work (but should be on the similar lines), other anti-radiation missiles like AGM-88 HARM, work with a passive radar seeker which detects enemy radar transmissions and homes toward it.
Since it is a passive sensor (like a camera, but for radar emissions), the only way to detect an incoming anti-radiation missile is by detecting the incoming missile by radar. Since often missiles are sleek and have a small RCS, it is difficult.

Many new-generation radars have a built-in protection system for anti-radiation weapons, which includes switching off the radar if any such threat is detected. In such a case, the anti-radiation missile continues to fly towards its trajectory determined during the initial passive lock using INS.
So here is the caveat, if you detect the missile early on (and switch-off the radar), chances are the INS is not accurate enough to guide the missile pinpoint to the previously-emitted radar, and it fails. If the radar is mobile, the best bet might be to quickly relocate the radar to a safe distance.

The anti-radiation missiles can also be "spoofed", by using a decoy emitting radiation (an open microwave might even work!). So when the original radar is switched off, the anti-radiation missile homes to the decoy. But of course, new missiles may come with ECCM capabilities to evade such decoys.

Coming back to "jamming" the NGARM, it makes no sense. You can jam an active sensor, not a passive "detector" sensor. You, however, can "spoof" it, or employ other countermeasures.

I think something this new will have two way data link option for mid-course correction & not a dumb home-in missile... Can't say for sure, but likely.

Two-way datalink does not solve the issue. What will the mother aircraft help with the datalink? If the enemy radar is switched-off, then there is no way of detecting the radar (except using SAR, but for that, the mother aircraft have to be close enough, just what we are trying to avoid by using anti-radiation missiles from standoff distance).

Would the mmw seeker it's rumoured to have help, but does the radar have a way to classify whether a missile flying towards it is a harm or something else. How does it decide to switch off cause there is a possibility of dummy missiles being fired at it.

 

[Haldilal]

Ya'll Nibbiars The ordnance workers are making the case for privatisation. If they can go on strike in the middle of a military standoff for some tantrum of theirs, they should not be in charge of military supplies.

Bold, Highly unlikely I will say. MMW seeker will also have to identify the target as radar from the standoff-distance (can be more than 80km in some cases).

does the radar have a way to classify whether a missile flying towards it is harm or something else.

Simple case, you can check any fast-flying small object rushing directory towards you

How does it decide to switch off cause there is a possibility of dummy missiles being fired at it.

Better safe than sorry. Dummies are often used in war to misguide the enemy.

What's the difference ?

AESA ground scan can track it once detected.

What's the difference ?

corporatisation is management reforms, privatisation is selling partial or complete ownership to private companies.

Many PSU’s went thru this process of corporatisation in the past, especially in power sector.

So rudram is an ejector lunched missile.....so ejector lunched astra won't be a difficult task

 

[FalconZero]

A side note, if the reported speed of Rudram-1 is true, that is 2 mach, then it can cover it's max operational range in less than 4 minutes, 150km here, so the target will have less than 4 minutes to detect and apply countermeasures.
Only two things that they can do in that regard is :
1) Actively detect the threat and shutdown the radar/target + move it if possible (given they have less than 4 minutes to do so they can't do much about that)
2) Use decoys which can confuse the missile with similar em wave

 

[mist_consecutive]

So rudram is an ejector lunched missile.....so ejector lunched astra won't be a difficult task

Isn't NGARM & ASTRA have the same body? So if NGARM is launched using ejector rails, that will mean ASTRA is also ejector rail capable.

 

[Tuco]

So if NGARM has a dual pulse motor with 150km range, are we looking at a similar range for Astra MK2 same motor may be used.

 

[Dessert Storm]

Further information on NGARM

 

[Ultramarine]

1) it is a indigenous missile
2) Anti radiation missile is a very rare missile class in defence industry, now India has a domestic solution.
3) earlier option available for IAF was IAI Horop, Now we have a replacement.

Harop is for autonomous and long distance targetting and more of a niche weapon and not carted on a warplane. We have had other imported anti radiation missiles like the Martel on M2K and the Kh-31 family for MKI for quite some time now. But yes as you have correctly surmised, this is an indigenous weapon and with many probable spin-offs.

 

[Bajirao]

Isn't NGARM & ASTRA have the same body? So if NGARM is launched using ejector rails, that will mean ASTRA is also ejector rail capable.

Astra 2 will be ejector lunched.....astra is 160 kg ,ngarm is 600-700 kg..

India test-fires Rudram 1, its first anti-radiation missile to kill enemy radars

India on Friday successfully test-fired Rudram 1, the tactical anti-radiation missile that the Indian Air Force can launch from its Sukhoi-30MKI fighter jets to take down enemy radars and surveillance systems. The missile has a launch speech of up to 2 Mach, twice the speed of sound, people familiar with the matter said. The Defence Research and Development Organisation developed the new generation weapon. It was tested at the interim test range Balasore, off the coast of Odisha in the Bay of Bengal, at about 10.30 am. “This is a huge step forward,” a senior government official said about the DRDO’s successful test firing. “The IAF will now have the capability to perform SEAD (Suppression of Enemy Air Defence) operations deep into enemy territory to destroy enemy air defence setup,” the official said. This would allow the IAF’s strike aircraft to carry out their mission unhindered effectively. “This test demonstrates the capability of an Anti-Radiation Missile with large stand-off ranges,” a second official said. The New Generation Anti-Radiation Missile, or NGARM, is integrated on Su-30MKI fighter aircraft. Its range depends on the height at which the fighter jet is flying. It can be launched from a height ranging from 500 metres to 15 km and can hit radiation emitting targets within a range of 250 km. All radars and Electro Optical Tracking System tracked the launch and point of impact, a senior government official told Hindustan Times. The tactical, air-to-surface anti-radiation missile is equipped with a passive homing head that tracks sources of radiation of a wide range of frequencies. It can lock into a target not only before launch but also after it has been launched. The missile is comparable to the tactical air-to-surface missile AGM-88E Advanced Anti-Radiation Guided Missile that was inducted by the US Navy only in 2017 and can engage relocatable Integrated Air Defence targets and other targets equipped with shutdown capability. This means that if the enemy shuts down the radar after the missile is launched, it will still hit the target. Defence Minister Rajnath Singh tweeted his congratulations to the DRDO team that developed the supersonic-capable missile that can be launched at speeds ranging from 0.6 Mach to 2 Mach. “The New Generation Anti-Radiation Missile (Rudram-1) which is India’s first indigenous anti-radiation missile developed by DRDO for Indian Air Force was tested successfully today at ITR, Balasore. Congratulations to DRDO & other stakeholders for this remarkable achievement,” Rajnath Singh said on Twitter.

Not 150....upto 200 km..
