Not to sound like an F-22 cheerleader but I thought this was interesting. . .

Every semi active radar guided missile system is an inherently bi-static system
and if get close enough to target even small missile antennas could pick up
returns.


There are several problems with that.

1. The nature of your radar and target are such that the missile is
going to need to be approaching the aircraft from any number of
directions meaning you're going to have LOTS of launchers.

2. The nature of your radar and target are such that something as
simple as the aircraft rolling ten or fifteen degrees could drop the
return so far that the missile loses it.

3. Your "transmitters" are going to be operating over a LOT of
different frequencies so your missile's seeker will have to see ALL of
them and they'll be changing from moment to moment both in freqency
and location as some turn on and some turn off. It won't be in a
predictable or controllable order to the user either.






Active homers need only an command link to put them in close vicinity of
target.


Active homers also need the return to bounce straight back toward them
too. The very thing stealth is designed to defeat.





2. With SDB you can hit *many* targets in one pass. With the wing
kit on them they have a range in the 30 to 50 mile range.

30-50 m range is not bad but pretty useless aganist 500-600 miles multistatic
tracking and detection ability ,specially if your opponent has fighters with
good range and long range SAMs.

Figthers don't have multistatic radars. Long range missiles cost big
$$$. If the need came up (meaning if hell froze over and we actually
saw any of these systems in service) we could just slap a small
turbojet on the SDB and be back in business.





3. About the best way I can think of would be to use the imaginary
radar system to find the x,y,z coordinate of the aircraft, fire off a
FAST surface-to-air missile that has a good IIR seeker. Send periodic
updates to the missile until it's close enough to see the target.

You are on right track but anyway if you come close enough to target any
receiver could pick up echoes or any active homer can lock on even if the
receiver or active homer is inside frontal threat cone.


Because you say so? Do you even know what you are talking about?
Hell the targeting device could be a satellite.




The weak links I see are the transmitter that sends the update though
they could make it so 99.9% of the time it's off the air except for
when you're making sure the missile has the right target, but even
then we're talking seconds. Also

Right,generally multistatics are more vulnerable to some forms ECM than
backscatterers,even without considereng missile datalinks.
But if you rely on active ECM instead of passive stealth for penetration ,thats
a totally different ballgame again.


You've still not shown any reliable source claiming that such a system
is even in developement. I'm talking about a system of
detection-to-shooter not just some one-off. And as soon as they come
up with a real system that will introduce comm links (it will have to)
and guess what the first thing is that will be knocked out? Face it.
Stealth isn't magic but it's the next best thing.
