The EOTS of F35/J20/J35 uses the MWIR to reduce the sensor size and it's a compromise to detection range to maximise stealth... But seperate IRST of AMCA will have LWIR, which will be highly effective to detect even stealth targets ( in spite of having cooling systems) at much longer range than the EOTS ( with MWIR) of F35/J20/J35... Here the main challenge for ADA is to make the upper nose IRST ( with LWIR) of AMCA in such a configuration so that it's radar/RCS signature reduced to the minimum... either a STEALTHY SAPPHIRE DOME or, Retractable IRST system ( or, something else) can be used... This will also be a trade off in between Longer range passive detection power ( even for stealth targets) VS the RCS reduction of AMCA's own body.... The seperate EOTS of AMCA will be mainly dedicated to Ground targets detection, identification & mapping.
Yes, saw it already, good you shared it, i was also going to share it. I subscribed him long back as he makes technical videos.
I'm also briefly aware of LWIR/MWIR/SWIR, their penetration & apps on detecting different heat sources, chemicals used for sensors.
Few pages back on page-104 i gave example of block diagram of F-22's cooling system.
Long back in 2021, on page 51 i said that F-35 DAS can pick up missile plume with 10x digital zoom at 1,300 Kms. Hence AMCA team will need to test different band sensors like USAF tested with airborne pods - ATIMS, TIGER, SARIS, ARMS, BASES, CIGARS, SATIRS, SEAIP, etc.
Does not having a mid-rib bang in the centre of an already cramped IWB limit your choices of weapons? Since it essentially partitions the IWB into two halves. Wouldn't it have been better to mount the hydraulic piping on the IWB roof scattered around the weapons mounts (& do away with the mid...

Then i compiled some searched data -
So i'm not sure which band & sensor is best bcoz SWIR would be emitted more by exhaust i guess.
If LWR is needed then it seems the sensor will be made of Zinc Sellenide/Sulfide, Germanium, etc, which may not be put behind a regular glass or Sapphire, etc. So imagine stealthy faceted sensor of Rafale's OSF or EF-2000's Pirate IRST.
As example if a missile is detected at 100 Kms, the jet is flying at Mach 1.5 & missile at Mach 4, then relative closure speed = Mach 5.5
Then 100 Kms will be covered in just over 53 seconds.
Some pre-determined strategy & tatics will be needed to dodge the incoming missile depending upon single/dual pulse.
But 5gen & 6gen tactics is to sneak from unexpected direction like pack-hunting. That's why
DAS arrangement of sensors with IRST function is important.
