Stealth cloaking devices
William K.   10/4/2011 1:11:39 PM
This is a great idea, and intuitively it should have occurred to somebody some time ago. I do see a serious source of trouble in one area, where it mentions the wireless control of the system. It would not take very much for an enemy to "listen a bit" and understand the control commands and then use their ECM capabilities to switch the system to serve as a target marker instead of a very clever cloaking system. So an independant wired control package would be much more secure and reliable.

It is interesting to note that a very similar approach has been used to thwart detection by building security system IR motion detector systems.

Avoiding friendly fire
Charles Murray   10/4/2011 3:17:47 PM
Although I'm sure this is always a consideration in a design like this one, it's the first time I've ever seen mention of "avoiding friendly fire." It stands to reason that if a vehicle is hard to see and identify, it must be equally hard to identify for friendly troops.

Seems like there a numerous use cases where technology like this can really make a difference. William raises some notable concerns, however, over what's stopping enemy communications systems from tapping into the signals and making the camoflauged vehicle a target. No doubt, subsequent designs will address that issue.

In an odd peacetime application do you think you could use your armoured car to program your VCR from like a kilometer away. Frank.. did you set the recorder for days of our lives.. no hon I forgot but don't worry. I can see our house from here. I'll just use the armoured Winnebago..

or.. Somewhere in Afghanistan:

The new armoured trucks have arrived..
How do you know are you like psychic man...?

on a serious note I can think of many tactical applications for this technology from using sheets of these panels to pretend to be aircraft or other military hardware in a place while the real assets are moved off. This could seriously improve the tactical advantage of "the cover of darkness" since FLIR devices have become so prolific. Maybe airforce or carrier aprons' could be coated in panels to change the appearence or the number of aircraft.  The mind boggles at the possible applications.

I agree it is a good idea, but I certainly hope this is to enhance Up-Armored vehicles and not replace Armor.  With most attacks being from small arms such as AK-47's and IED's, which don't use thermal imaging, this would certainly not provide soldier protection in most attacks.  If you are being targeted by a tank, helicopter or something that used thermal sights, it would be a good camouflage.  But don't confuse camouflage and detection with concealment and protection.

William,

There is no technology needed to avoid detection by building motion detectors. Just move real slow and you can move through a room full of motion detectors without being detected...

I used to have IR detectors downstairs and around a previous house and experimented quite a bit with the sensitivity level to avoid detecting pets and other critters scurrying around, but found that they are easily fooled when you reduce your normal speed of movement, since usually their detection is based on the amount of change per time per segment they monitor. So a slow-moving big object does produce the same levels as a quick moving smaller object. In other words, either have the false negatives of smart slow-moving tresspassing humans, or have the false positives of every cat or other animal moving around. Not a sleep-enhancing trade-off...

"large identifying symbol":  Is that another way of saying "painting a target on the side of the vehicle"?

The images included in the article is impressive.  You can just barely see the dark outline of the vehicle in the "ON" image.

If one wants to go totally cold as suggested, where does the heat go?  And the exhaust system of the vehicle, that's going to leave thermal blooms.

The plume, the plume the little heat sensor said

Comments: 

Hide the plume, perhaps it can be cooled, and perhaps spread on the ground on the far side of any enemy radar... 

Better hide, or transform, the vehicle sounds while you are at it...

Mimicking the back ground is needed otherwise as the "box" moves along a distortion area will be detected...I am referring to the fact that an outline can be seen, and that the space outlined does not look like the back drop....

How vast can it change images... if one is going to mimic the background, the system must be fast enough to display the background in a realistic way.

Somewhat off topic:  One could conceivably make an image of small cars going faster or slower that the cloaked vehicle... but it would be difficult to deal really well with the edges vehicle's silhouette...
