at 20-35,000lb thrust it's bound to be a bit warm. Hide that in the IR spectrum if you can. BVR is a funny term 'cos the Hubble telescope can 'see' to the edge of the universe.

OK. How about BER. Beyond eyeball range. A lot of people go on about the raptor's FCS. What about the BCS (behind cross section)? Is this beast a Jennifer Love-Hewitt or a Jennifer Lopez?

It's far more stealthy from behind than any non-stealth aircraft is from behind. I'd bet that, except for a cone of a couple degrees centered directly on the axis of the engines, it's a very safe assumption that it's more stealthy across the rear arc than any non-stealthy aircraft are across their front arc.

link Easy to see the extensive attention paid to rear aspect RCS

i wonder what tactics are being studied to counter a stealth fighter, i heard OSR is the best bet, which is the ticket the rafale is riding on

What about when it moves its rudders? Surely that would sorta ruin the stealth affect. You are changing the shape of the aircraft a little after all.

how does back scatter radar work? or is the term bi-static?

It is both. Low freq radars typicaly use separated Xmit and Rcvr sites to limmet interfirance. Stealth as we know it is worthless Vs Low Freq Radar. There are no possable air born countermeasures to LFR in a plane capable of flight beyond Mach one. NONE! Read DisplacedJim's post. It has the right take on Raptor's rear.

The Low Frequency Radar you are describing is commonly called over the horizon backscatter. The very long wave length used by such low frequency radar make it very difficult to pick out the relatively small target presented by an aircraft against the very large target presented by the earth - clutter if you will. Conventional clutter removal techniques, including doppler MTI, don't work as well with OTHR. By the way, ALL radars are backscatter radars - the receiver picks up "backscatter" from a target illuminated by energy from the transmitter.
