Re: LCA: News & Discussions: 15 August 2017
Aren't the current generation of IR seekers with ability to neglect the flares..? I thought they are. Its bit easier to differentiate and reject ultra high temp spots that flares create (It has Magnesium isn't it?). I was thinking now a days sensors actually target the relatively hotter (wrt background) airframe when they close in and not the exhaust hotspot per se. With increased resolution and computational power on-board, its possible to put better algorithms. But it could be so that flares also have improved over time. My knowledge is anyway limited on this front.shiv wrote:What is your exact objection?Indranil wrote: Frankly, I don't like that positioning of the dispenser canister. It doesn't fit in there completely and a fairing is added just in front of the the extra part that juts out. I hope they refine it further.
The interesting part to me is that an IR seeker directly at the back locking on to the exhaust will start seeing hot spots diverging away from the very hot spot (the exhaust) it was centered on and if the plane manoeuvres away only the flares will be left visible.
Re: LCA: News & Discussions: 15 August 2017
Hakeem,
My objection is not with the placement of the CMDS. My objection is that it doesn't fit flush with the surface of the aircraft. What is the use of smoothening out that trailing edge extension only to add CMDS canisters which are jutting out?
JayS,
Modern CCMs can decipher between flares and planes. If only one flare was released, it is unlikely to break lock. But if there were 10 flares, that may just be enough noise to overwhelm the processing momentarily to break the lock.

Re: LCA: News & Discussions: 15 August 2017
A little OT. The pic below shows how the seeker of a modern IIR missile like Python-5 will "see" the target. Apparently, they are designed not to look at the hot spots from turbines but the overall heat signature of the airframe.

^This is from wiki...
https://en.m.wikipedia.org/wiki/Infrare ... ng_systems
With iir systems the seeker is looking for an image generated by the source instead of just the heat. So if the flare does not look like the generated image the missile won't be spoofed.
But of course such missiles are hardly common and I don't think the tspaf has any in it's inventory.
https://en.m.wikipedia.org/wiki/Infrare ... ng_systems
My rather layman understanding is that older missiles seekers sought the heat being generated by the fighter exhaust and so could be spoofed by flares if the fighter simultaneously moved out of the seekers fovImaging systems Edit
Modern heat-seeking missiles utilise imaging infrared (IIR), where the IR/UV sensor is a focal plane array which is able to produce an image in infra-red, much like the CCD in a digital camera. This requires much more signal processing but can be much more accurate and harder to fool with decoys. In addition to being more flare-resistant, newer seekers are also less likely to be fooled into locking onto the sun, another common trick for avoiding heat-seeking missiles. By using the advanced image processing techniques, the target shape can be used to find its most vulnerable part toward which the missile is then steered.[45] All western Short-range air-to-air missile such as AIM-9X Sidewinder and ASRAAM, Chinese PL-10 SRAAM and Israeli Python-5 use imaging infrared seekers, while Russian R-73 still uses infrared seeker.
Countermeasures
There are two primary ways to defeat IR seekers, using flares or IR jammers.
Flares
Early seekers did not image the target, and anything within their FOV would create an output. A flare released by the target causes a second signal to appear within the FOV, producing a second angle output, and the chance that the seeker will begin to aim at the flare instead. Against early spin-scan seekers this was extremely effective because the signal from the target was minimized through the midcourse, so even a dim signal from the flare would be seen and tracked. Of course if this happens, the flare now disappears from view and the aircraft becomes visible again. However, if the aircraft moves out of the FOV during this time, which happens rapidly, the missile can no longer reacquire the target.
One solution to the flare problem is to use a dual-frequency seeker. Early seekers used a single detector that was sensitive to very hot portions of the aircraft and to the jet exhaust, making them suitable for tail-chase scenarios. To allow the missile to track from any angle, new detectors were added that were much more sensitive and in other frequencies as well. This presented a way to distinguish flares; the two seekers saw different locations for the target aircraft - the aircraft itself as opposed to its exhaust - but a flare appeared at the same point at both frequencies. These could then be eliminated.
More complex systems were used with digital processing, especially crossed-array and rosette seekers. These had such extremely narrow instantaneous fields of view (IFOV) that they could be processed to produce an image, in the same fashion as a desktop scanner. By remembering the location of the target from scan to scan, objects moving at high speeds relative to the target could be eliminated. This is known as cinematic filtering.[46] The same process is used by imaging systems, which image directly instead of scanning, and have the further capability of eliminating small targets by measuring their angular size directly.
With iir systems the seeker is looking for an image generated by the source instead of just the heat. So if the flare does not look like the generated image the missile won't be spoofed.
But of course such missiles are hardly common and I don't think the tspaf has any in it's inventory.
Re: LCA: News & Discussions: 15 August 2017
Not right now but its only a matter of time. The JF-17 Blk III is expected to include a HOBS-AAM (& HMDS), almost certainly the Chinese PL-10E (IIR seeker, 90 deg FoV). The older blocks will likely be retrofitted with it in due course.Cain Marko wrote:But of course such missiles are hardly common and I don't think the tspaf has any in it's inventory.
And while the US will not export the Aim-9X, I wouldn't be entirely surprised if the new Turkish WVRAAM in development made it onto the PAF F-16s at some stage.
Re: LCA: News & Discussions: 15 August 2017
The only way a missile can be programmed to look for an aircraft's IR signature is to look for much cooler spots other than the exhaust itself. If a bunch of very hot spots simply obscured the seeker's view of the cooler spots it could provide a window for the plane to turn away while the seeker is still searching for confirmatory cooler areas that conform to the general shape of an aircraft. At least that is my understanding...Cain Marko wrote:

Re: LCA: News & Discussions: 15 August 2017
The CMDS is easily reachable by the ground crew for replenishing quickly.
If they put it anywhere else, one would need a stair to reach it.
This is a racing car, which is supposed to have very short pitstops for refueling and replenishing. The IAF should also ask that the fast refueling also be incorporated in the IAF jets.

Re: LCA: News & Discussions: 15 August 2017
That is exactly what Cain Marko is saying and the purpose of IIR. It has to do with the granularity available from the different type of sensors. Besides, imaging (IIR) allows auto-correlation analysis as well for better tracking.shiv wrote:The only way a missile can be programmed to look for an aircraft's IR signature is to look for much cooler spots other than the exhaust itself.

Re: LCA: News & Discussions: 15 August 2017
Yawn.. Let me speculate here on what is the "feature" that is being people are so curious about.
1. Wet mid board tanks.
2. Centreline pylons cleared for tanks
3. Centreline pylon probably cleared to carry 2 * 500 Bombs. or 4*250 kg bombs or multiple rack of A2A missiles.
With that, what it means is that the with 2*800 kg rated mid board wet pylons, the fuel capacity goes up by 400 kg over carrying carrying 1200kg fuel in the centre line pylon. 400kg means approx 6.6% increase in the max fuel that the LCA can carry currently (6000 kg , 2400 internal, 2*1200 aboard, 1200 centre). That 400kg fuel is typically the reserve that would be kept in mission planning. So all in all greater flexibility in mission planning and probably more max range possible in strike configuration and will certainly put MORE legs and persistance on the LCA for all kinds of roles, including air defence.
Will this get reported to the "concerned folks" too ?

This stupid thing about you cant know this or you can't know that comes from the commie hangover our country has from Nehru-Gandhi era. There is so much stuff about LCA that ADA can easily share with public without having any impact whatsoever on its ability to surprise enemy (I guess they don't have enough motivation or even time to do that, too busy with work already). The amount of technical info shared, had it been in US or Europe, would be definitely far far more. Any dedicated and half decent aero engineer can get the ballpark performance figures of aero config of LCA, efforts would be significant but not so much that its undoable if he is hell-bent. If I were enemy of India and wanted to know LCA's performance I would put a team of a handful of engineers to make models and run them in WT and CFD to get a very good estimate of all key performance parameters. Its more difficult for stuff which is hidden inside i.e. the avionics. But I am sure the experts in that field can draw good enough conclusion from easily available information. There is really a small set of technical information which needs to be guarded closely. Majority of technical performance parameters can be estimated relatively easily if experts are put on the job.
