This was in some earlier posts....Torch said:There's been a bunch of new fighters coming out ex:Grippen,Rafael,Typhoon,F-22,SU-27,Migs etc. Is there anyplace to look up on how they would match up against each other? Or does anyone know if there's been joint excersises matching these planes up. I know India was bragging that they "defeated" a US "attack" with their Migs against F15's but that was a bit staged..
They did - one's sitting at Wright Patterson AFB...Nonskimmer said:Didn't the US purchase something like a dozen or so Mig-29's from Moldova a bunch of years back? No need to paint F-5's and F-16's to look like Russian planes when you've got the real thing.

The IAF defeated the USAF in Cope India excersizes - the F-15s could take on the 3 and 4 to 1 odds they normally defeat in these excersizes.
2 to 1 is a different story.
Aggie08 said:I read about them using the vectored thrust to manuever to defeat the F-15 pulse doppler (an old technique red flag has used).
How would that work?? How would it mess with radar?
lesofprimus said:Sounds like there would be too many G's for the human pilot to handle, pulling a perpendicular move like that, to show a radial velocity of zero....
Bullockracing said:I'm not sure I believe the radar wouldn't pick up a turn, no matter how sharp. I'll have to agree with lesofprimus on this one. The doppler effect when used on moving objects as it relates to tracking based on radar involves wavelengths that cannot be just "turned in between to show a radial velocity of zero". Once you turned, you would have to turn again, otherwise you would be "caught", so you would be in a vicious cycle of turns...
Bullockracing said:Pulse-doppler radar is based on the fact that targets moving with a nonzero radial velocity will introduce a phase-shift between successive pulses for the sample volume containing the target. Target velocity can therefore be estimated by determining the average phase-shift between successive pulses within a pulse packet. Real characteristics of a returned signal from a target may vary due to: wind shear, turbulence, differential fall velocity (particularly at high angles of attack), antenna rotation, and variation in refraction of microwave fronts. The generation of radar used in F-4s could be tricked into not seeing an approaching aircraft due to this differential fall velocity. All this being said, considering our thread, the radar in the current-generation of US fighter aircraft is more than capable of tracking an incoming adversary, regardless of thrust-vectoring, jinking, etc.
