[sci.military] Air defense

As a result of the Gulf War I am left with a number of questions about
our own air-defense capability.   Granted, the Iraqi Air Force was
never a major threat to Allied surface targets except for their Scuds,
but a future adversary might be.   Our bombing of Iraqi forces showed
how effective air power can be against military forces on the ground.

1.  Wouldn't the Patriot system be a sitting duck for HARM -type weapons?

2.  Is there any reason to assume that our own air-defense would be any
more effective against modern aerial attack than the Iraqi air-defense
system was?   Are our SAMs or AAA considered significantly better or
less vulnerable to countermeasures than the Soviet-supplied systems the
Iraqi's used?

3.  Is there currently much work being done on *passive* AAA or SAM
guidance systems?   One thing the Gulf War showed was the effectiveness
or antiradiation missiles.  Often the Iraqis wouldn't even turn their
radars on for fear of drawing fire.   But it seems to me that modern
sensor technology such as that used in LANTIRN systems combined with
modern image-processing, which ought to easily be able to distinguish
the shape of an aircraft from that of, say, clouds or contrails, would
allow AAA to be guided without emitting.  In fact, I suppose a passive
IR system could "illuminate" its target area with occasional magnesium,
thermite, or other high heat-output shellbursts, requiring no
particular accuracy.

4.  Does anyone employ radar decoys as HARM countermeasures?  It seems
to me that you could build radar transmitters, requiring no particular
frequency stability, quality, or good antenna *real cheap* (If it were
me (N1CHJ) I guess I could do it for $1K apiece, the Army might spend
an order of magnitude more but that would still be cheap.)
