When you have time and/or the inclination could you elaborate on what exactly is:
veiling glare lasers
undetectable comms
no-probability-of-intercept radar projects
Project Sheriff segments
Ning Li's lab
SCIF
CAG USAPs
EM flux you can hang popcorn on the fence for a snack
thanks
Wow, ok, here goes. Generally this is where I end up saying "oh, you mean that's not out yet? Whoops!"
Veiling glare laser:
There are wavelengths of UV light that make your corneas, lens and the aqueous humor of your eye fluoresce bright yellow green. This has the
not-too-unexpected side effect of making you blind while the beam is on you. The general term for any effect that keeps optic systems from working due
to extraneous light sources in the optical path is "veiling glare". That's why telescopes have tubes, your eye is opaque except for the cornea,
etc.
So, you can tune up a dye laser (or, now, some semiconductor ones) that puts out just that color. Voila! An anti-pilot weapon. When it's on you,
it's like your head's in a big green plastic bucket with a bright light shining on the outside. It's hard to explain if you haven't been hit with
it. Very disconcerting.
It's been euphemistically called the "pilot error beam", although technically it's a veiling glare laser.
Undetectable comms/ZPI radar:
Uh...you haven't heard about this yet? Kirtland is running tests on the effects of ZPI on people now, unless they completed it already. No one knows
quite how it affects people at high power. Can't deploy it on the flightline if you don't know what it does to the ground crew.
It's UWB taken to the end result. Basically, you take the outgoing signal and smear it from "DC to sunlight", which is the technical euphemism for
a perfectly done non-interceptable comms implementation. In a perfect engineering model, the energy in the signal at any one frequency approximates to
zero. So it "vanishes" beneath the background noise. You have to have the time domain characteristic of the signal to recorrelate it out of the
background noise. It's the end result of the Army's "sneaky wave" projects. There's a long long tale about that which I'm not privy to pass
on.
Anyway, done with handheld comms it's not only not able to be intercepted if you don't have the key, it's incredibly transmit power efficient due
to a weird quirk in the math that makes the antenna look like it has spectacular gains.
There's other neat side effects, the receivers always know where the transmitter is relative to them. So you can get a fix on your buddy without
triangulating.
Done with radars, the power is lower, the efficiency trick works there too, and again, there is effectively no power at any one frequency. You have to
integrate a range of frequencies to see it, and you have to have the "key" to do that. There are a lot of advantages that I bet they'd rather I
didn't go into details on, but just not being able to intercept the emissions is great enough.
I've seen some real-world military devices already out that use the general trick that they have down in Tampa. The new visibuilding project will
probably use it for imaging inside the building. There's a lot you can do with the basic concept.
Project Sheriff:
Oh, you ought to be able to find a lot about that. Just look for Project Sheriff on google. Bits and pieces of it were done in the Huntsville area. Or
at least passed through for analysis.
Ning Li:
She is the queen of anti-gravity. Did some paid-for projects for NASA, got half a million bucks, used it to fund some basic studies on her device and
no one knows where she went. Or at least I don't. Used to be AC Gravity. Dr Li took off suddenly for parts unknown around 2004, I tried to track her
down several times, no luck.
SCIF:
Sensitive Compartmented Information Facility (I've also heard "secure"), it's the gubmint's name for the TEMPEST rated bank vault sort of room
you work in when you're doing classified stuff. We had one in Huntsville and one here now.
EM flux/popcorn:
It's legend that you can pop popcorn if you hang the bag on the Arsenal fence over by the officer's row, when they're doing a missile test, due to
the missile tracking radar. It's acknowledged that if the guys that work there are going to all get cancer from it, at least the officer's kids will
have three eyes, a very rare concession in the military. Usually the NCO housing would be there so that the sergeant's kids had tentacles. The
view's nice though, can't have that.
If you want to track a small very fast moving object accurately, you have to throw a lot of radio power downrange. And there's all sorts of radar
going on all the time there.
It is true that you can't do an open field test very easily anywhere near the base. Wyle Labs can do one but they use magic. And there's times the
background EM level is really too high even then.
CAG USAPs:
Combat Application Group Unacknowledged Special Access Projects. There's two biggies not too far away. It's fun to go watch them get antsy when you
drive by to look at it. As long as they don't get TOO antsy.
