I felt I should make a new thread for these since there are many. These papers are by people closely affiliated with Pakistan's military R&D. Unfortunately, they are published in less-than-renowned places and therefore hard to get your hands on. I am posting them here for everyone's benefit. You can see many interesting things if you just scroll through them.

Multi-frequency analysis of Gaussian Process modeling for aperiodic RCS responses of a parameterize aircraft model
This attempts a ML based RCS estimator - uses JF17 for validation

Actual RCS numbers..yeah...








Comparison of SBR and MLFMM techniques for the computation of RCS of a fighter aircraft
Some RCS computation method comparison.

ISAR imaging using FFT with polar reformatting of measured RCS

Some research into detecting stealth fighters...but uses designs from Azm

Guidance and control of standoff air-to-surface carrier vehicle

GNC of IREK....you can even see a weird REK design which I guess was one of the initial designs:

desired range is 100-120 km

F23 was said to be better design than f22

Better Stealth but less agile than F 22.

It is not just choosing the desired design but also on how our technology can actually develop it. Since 2011-Desember 2012 ADD Korea and Indonesian team (Indonesian Aerospace+ Institute Technology Bandung) make 2 design of KFX/IFX, one with canard and the other without canard.

This phase is also known as Technology Development phase where the optimum designs are made, but later the one without canard that is picked ( C -100 ) to be developed further and refined. One of reasons the canard design is not picked is because of the fact that we dont have capability to make one with canard, look like related to its FBW system.

KAI and LM entered the program since 2015.

Brother, actually what is your specialty in Aerospace engineering ? And I would like to know whether you are involved in fighter project in USA since you have got Master and Phd degree in US and possibly currently working in US Aerospace industry as well.
