Is it possible to convert su-30 into stealth or semi stealth?

[Skull and Bones]

You can buy an F-15 Silent Eagle for $100 million.

But yeah, $180 million for a Russian bird sounds a bit much.

Guess its better to wait for the FGFA.

F-15 isn't stealth at all, its just a low observable aircraft. It'll have a RCS of around 1-2 sq meters. As you might have noticed F-15SE doesn't have maximum parallel surface as present in F-22 or F-35. Rounded surface on F-15 SE reflects radar waves back to the source thus it's not complete stealth.

look at the area near the air intake, so unstealthy.

Are you sure the SU-30 has canards?

Yes, indeed. Su-30MKI has canards.

 

[Vibs]

Air-intakes has to be changed, canards has to be removed, horizontal stabilizers has to be inclined to coincide with the shadow region, stealth without internal weapon bay is laughable. And present Su-30MKI costs more than $100 million a piece, with all these upgrades Su-30MKIs will costs more than $180 million.

So is it economically viable when you have a stealth fighter jet around the corner?

Once again RCS is irrelevant today. The Su 30 MKI has DRDO Tarang Radar detection system which provides early warning of Radar waves reaching the aircraft and the Israel developed Elta EL/M-8222 jammer which jams the radar waves making the aircraft invisible to radars. The air-frames, body,RAM coating etc etc does not even need to come into play.

Only thing remaining is the infrared signature which engineers are working on now.

Actually newer MKIs are using Tarang mk2 which is a radar warning jammer.This system can detect incoming radio waves from 400 km,can guide the Kh-59 Kripton anti radiation missile without using the bars PESA radar and has a digital radio frequency memory.This system stores frequency of a radar and jams it through either thd internal jamer or external Elta 8222.The new system is capable of noise,barrage and diception jaming and can jam multiple jammers.

Jammers can't jam AESA radars. So RCS reduction is indeed necessary.

 

[Vibs]

Jammers can't jam AESA radars. So RCS reduction is indeed necessary.

Aesa radars rely on the fact that their frequency changes continuously and cannot be identified and countered by jammers. However AESA radars work as recievers as well.

Under “Super -30” Project, Su 30MKI will get Russian Phazotron Zhuk-AE Active Electronically Scanned Array AESA radars along with new onboard mission computers, electronic warfare systems.

So if both have AESA's the power and agility of the AESA’s beams can be used as a weapon, jamming or even frying out enemy radars.
Fact is that both parties despite their AESA radars would not have spotted each other but would have launched Electronic counter measures based on the radar signals they detected.

 

[Skull and Bones]

Not entirely true.

The power and agility of the AESA’s beams can be used as a weapon, jamming or even frying out enemy radars. In other words, it can listen to the frequency of the bad guys radar and send erroneous returns or even a deadly pulse back to that radar, blinding or even crippling it.

A jammer samples and filters out a definite radar signal and emits a radar wave having a phase shift from the actual radar signal which in turn cancels out the incoming radar signal to a great extent but not entirely.

And in a present day battlefield, an aircraft will be flying in the tracking range of several radars operating at different frequencies, so its not possible to sample out and jam every radar signal in the vicinity. And if the enemy radar is AESA, then forget about even jamming it.

 

[Omega007]

Jammers can't jam AESA radars. So RCS reduction is indeed necessary.

Suppose we reduce rcs of Su 30MKIs to 3 squre meter.Now you can not fit an internal weapon bay because MKIs generate lift through the space between uhe engine intakes.So you have to mount all the loads externaly and the rcs will again go up exponencialy.Today's AESA radars can track 3 m sized objects from more than 240 km away.So rcs reduction of 4th generation fighters don't make a lot of sence.Instead if you can install a solid state multy beam active barrage jammer(which DARE has developped) that can jam the datalinks of fighters,AWACS then you can render most BVRAAMS useless.That's why barrage jamming is so devastating and even the US has contributed lot of resources to develop and deploy the EA 18G growlers which use multiple active jammer pods to make a powerful barrage jamming network.Hope I did not bore you much.

What is relation between RCS and Stealth. if body(airframe material) is raddar absorbant what will be the difficulty regarding big/more RCS.

"solid state multy beam active barrage jammer"
what is this? any web or article.

Let me repeat the point I made above in brief. Traditional radar detectors and jammers cannot detect AESA, I give that to you. But an AESA can detect and jam another AESA.
The next line of upgrades for Su 30MKI is the inclusion of AESA and electronic warfare equipment.

Explain the process of the highlighted part? How can you sample, filter and emit the radar waves which keeps changing frequently?

A link explaining the same will be helpful.

Well said buddy.Each t/r modules in an AESA radar works in different frequencis and change their frequency so quickly that it becomes impossible for a jammer to jam an AESA radar.But today's powerful solidstate active barrage jammers can jam datalinks of fighters,AWACS and missiles,stoping their guidence render the BVRAAMs useless.Growlers use the same principle.
By the way Phazotron-zhuk AE is still not finalised for Super 30 upgrade.

What Mr Vibs tried to say that if your fighter has an onboard AESA radar powerful enough(atleast a peakpower of 30kilo watt)then you can fry the opponent's electronics by concentrating your AESA beam towards the enemy fighter.He should have used the word 'fry' rather than 'jam'.
The F 22Raptor can do this with its AESA radar whibh has over 2000 GaN t/r modules.Check their website.

An AESA is not a conventional radar.It's more like a super computer system on your jet. These systems consists of thousands of tiny radars that can be independently aimed in different directions. Each radar can pick and transmit numerous frequencies.
For developments of the AESA for use as a Electronic Counter Weapon go to Raytheon's site.

what is dare and is India using the jammer which you mentioned ?

[ptltejas]

Barrage jamming: jamming accomplished by transmitting a band of frequencies that is large with respect to the bandwidth of a single emitter. Barrage jamming may be accomplished by presetting multiple jammers on adjacent frequencies, by using a single wideband transmitter, or by using a transmitter capable of frequency sweep fast enough to appear radiating simultaneously over wide band (e.g. a carcinotron). Barrage jamming makes it possible to jam emitters on different frequencies simultaneously and reduces the need for operator assistance or complex control equipment. These advantages are gained at the expense of reduced jamming power at any given frequency. Barrage jamming has to be used against frequency-agile radars, which change frequencies too quickly to follow them in a conventional way. The use of Barrage jamming may also affect the communications capability of the jamming source in a negative fashion.
