Um Ok
thermographic does penetrate, it follows through shallow land mass and deep water for subs, IR can be blocked even on a cloudy day but IR is not used for that the military uses IR to track heat from say and ICBM not for soldier tracking via the HumanID project. These projects are outlined in detail one need just go to DARPA and look or follow links I have listed on other posts regarding this matter.

So you're saying that when I'm enjoying the pleasure of my own company (about seven times per day, more on weekends) that the whole country could be watching? I guess I better be more discreet...

This doesn't make sense geometrically. If you can do it with three, it means that you've got 180 degrees between at least two of them, which means you could do it with just two and have 180 degrees in all directions. If two isn't enough I think you'd need at least six.lerichards said:
You contradict yourself. Something as wispy as a cloud blocks IR, but the solid tiles on the roof of my house, don't? Are you talking about active, or passive detection, btw? Doesn't make much difference either way, IR would still be blocked by a solid object, just check out the refractive indices of any material for IR.
IR does not penetrate sea water very well, btw, there is too much reflection and scattering, and sea water filters light, especially longer wavelengths out very quickly. If you have ever dived, and ever cut yourself at depth, you'd know that blood appears black, because there is no red light to show it as red, so your claim of 'deep water' is just not borne out.
Read my post again .
I said 'thermographic does penetrate, it follows through shallow land mass and deep water for subs, IR can be blocked even on a cloudy day but IR is not used for that the military uses IR to track heat from say and ICBM not for soldier tracking via the HumanID project.

The point you said I contradict myself on is not valid because if you read I said those things about thermographics NOT IR I specificly stated what thermographics and IR are used for. I was agreeing with you on the IR point though.
Thermographic is IR.
Infrared radiation has several wavelengths but each is different. I understand they fall under the 'IR' but there is a big difference between say the spectrums used for night vision and that used for thermal imaging.
Each region does different things and has unique capabilities and limitations as i'm sure you know.
Long wavelength infrared or LWIR is the spectrum used for thermal imaging. The resolution of normal sensors is limited by the wavelength of radiation.
The Quantum Sensors Program is applying phenomenology from quantum mechanics to improve the performance by decoupling of optical wavelength and optical resolution which provides a basis for high resolution sensors. This new way is far better then even the KH12 improved crystal satellite.

Space-Based Infrared System done by Lockheed Martin Space Systems use several satellites in geosynchronous orbit as well as fixed and mobile ground assets [known as Eagle II] to receive and process the infrared data. SBIRS is allready in use and the last phase is the low orbit satellites you can see that information here.

High resolution satellites that will be launched over the next several years (such as Iknonos, QuickBird and OrbView) and some that have allready been launched use Quantum Dot Infrared Photodetectors and Imaging Arrays to increase there capabilites.
All these projects are in there 3rd and 4th development stages and there early versions are allready in use.
Here is a couple site that gives an idea of several programs that are in use and are coming.

Another aspect of current 3D imaging software is that it takes information from several means satellites just being one of them with that information the software can give real life and near real time imaging.
Our technology has gone past the point that just one system is used to gather information from space. The current technology is way beyond even what it was just a few years ago and the information given to the public represents WAY out of date technology.

None of that escapes the fact that roof tiles are opaque to IR, and that satellites cannot use IR to see you inside your house, nor penetrate 'deep' into the sea.
Thermal IR, is about 1100nm. So a bit smaller than millimeter wavelengths. What's your point?
What does the government want with any of the information that it gathers?
Are you following this thread? The claim by the OP was that spy satellites can watch you inside your own home, ... that was not backed up.
You then compounded this fallacy that it can be done using thermographic IR, and didn't back that up.
Metakron then asked about millimetre wavelengths, ... something I have not mentioned. BTW, if you didn't know, Thermal IR, ie, the Thermographic part of the IR spectrum, rather than near visible, is about 0.0011mm, three orders of magnitude, or one thousand times off what Metakron is asking about. So, why should I justify him with an answer when I have made no claims about millimetre wavelengths, and thus far, neither has anybody else? It's tangential, and diversionary.
can you prove that roof tiles are all that opaque to all those wavelengths, including millimeter wavelengths?
this was a question about the roof tiles not what the wavelength was.
as for "proof" it is expected that one would say that is not right BECAUSE then give a reason, THEN back it up.

Hey bub, maybe you dont understand how this works. I have not made the claim that satellites can see inside houses. I have not made the claim that Thermographic IR is used to facilitate this either. That was the OP and you.
You back that stuff up, eh? You made the claim.
Like I said, I don't give a rat's ass about millimeter wavelengths, it's a diversion by Metakron. You also haven't answered whether we are talking about active, or passive detection btw.
Clearly you don't understand refractive indices and extinction co-efficients. For any given material, these are a function of the incident wavelength. IE, some materials are opaque to some wavelengths, and transparent to others. IE radio waves will pass through materials that visible light cannot, but you can see through the mesh of a Faraday cage, but not pass a radio signal through it. Get the idea now?
