But what about the allegation that independent testing of the aircraft in realistic scenarios using actual Russian radars and jets.
Not a valid criticism.
To start off, Nellis have the 507th Air Defense Aggressor Squad...
http://www.nellis.af.mil/News/Article/284637/one-of-a-kind-squadron-trains-airmen-from-ground-up/
The 507th uses Soviet/Russian equipment to provide real time radar threats training to guest and host units, meaning a unit can come to Nellis, or the 507th can go to a unit's home base. There are many reports that when -- not if -- unleashed, the 507th 'killed' all attackers. That does not mean such will happen in real life, but what it means is that an un-trained and unfamiliar unit will face an EM threat that they may not be able to recover against. Once a unit is trained and familiar, that is a different, and classified, story.
But to get technical about it...
This is the foundation of
ALL pulsed radar systems...
From that, we can create much more complex pulse characteristics like this...
Pulse complexity depends on the level of computer and software sophistication.
Currently, there are no credible technical sources that says X country is able to create radar pulse characteristics that the US cannot replicate. We have SIGINT flights for this reason. You better believe it that we know %99.999 of what the Chinese, Russian, Iranian, and North Korea has.
What little has been performed shows the aircraft is prone to displaying ghost targets.
This is a loaded statement. The word 'prone' is interpretative.
Ghost targets can come from many sources, including one's own hardware design, of course. But ghost targets can also come from environmental factors such as weather or from aircraft maneuvers that affect the relationship between aircraft and target.
The Doppler component is one such external factor. No radar is immune to that. If the conditions are Goldilocks, meaning 'just right', even for a second, the radar will momentarily lose track and/or lock. This is real physics. Not 'Iranian physics' or 'Chinese physics' as it is well known in this forum that those two groups love to distort the laws of nature to suit their arguments.
What is also real physics is that if another radar at a different location is looking at the same target, that other radar
WILL NOT see ghosts. The angular and Doppler differences are -- different.
So if you have two F-35s, one pilot is not going to say: 'Hey Maverick, this is Iceman, can you check coords X, Y, and Z ?'
No, Maverick and Iceman will be informed by their F-35s of the calculated location of that target as compensated by each jet without prompting by the pilots. In the old days, as in when I was on the F-111 and F-16, we cannot even communicate by voice to each other to have this kind of verification. Today, the F-22/35 can do autonomous cross checking as soon as they know of each other's presence. Now you add in AWACS and/or ground radars that can do the same thing.
No other air force can do this at this time and probably not for the next 20 yrs.
The only counter Berke had was "it performed very well in Red Flag". Well Red Flag is almost all US jets, whose radar and system capabilities they know like the back of their hands. It is also not an independent test because the same airforce leaders who are backing F-35 were involved in planning and executing Red Flag.
Go find Pakistani pilots who have been to Red Flag and see if they take that criticism seriously.
The core of Sprey's venom against the F-35 is that the entire program is corrupt, from top to bottom. No one is honest. Anyone who speaks positively of the jet is either a dupe or in the pay of Lockheed. I put it at the same absurdity as 9/11 is an 'inside job'.
