If you are worried about FLIR or other thermal detection, find an olive drab space-blanket or, even better, a "combat casualty blanket" which is a heavy padded version of a space-blanket, and convert it into a cover for you position.- Warhawke |

Blown out and about, the human can wander through the fog with more immunity from being seen. Not that the FLIR would not pick it up, but rather that the scatter effect of the water particles, especially if warmer than normal atmosphere, will also obscure any actual positions. |

These would have to be aimed at the FLIR, but that is usually not too hard. The best way to do this is to use the battery powered, high output halogen style IR flashlights. These can have devastating effects on all kinds of digital camera receiving arrays. The IR light, if of a high enough intensity may blind the FLIR permanently or for over 5 minutes (time it takes the ccd to clear and recharge).

Moisture and dust are cited in the wired article, active jamming as in your suggestion would require exposing yourself via your beam not an optimal solution. Decoy or causing sensor bloom by providing an overwhelming heatsource may or may not work depending on the software limiting the protection of the sensor I am interested in a passive solution to overhead surveillance in an urban environment. Pattern matching thermal clothing which will thermally break up the heat image of the human body to mimic something else..Plant or animal perhaps |

Anonymous Coward (OP) User ID: 891172 United Kingdom 02/14/2010 05:01 PM Report Abusive Post Report Copyright Violation | news in the INCOMING blog as well as update the Show Archives as we can. « Israeli Organ Harvesting News Thoughts about Flinching » Infrared Imaging Countermeasures from SurvivalBlog There are several proven, low cost techniques that can be used against thermal/infrared imagers. But none of them last an extended period of time. While they are not fool-proof they certainly do work well enough to frustrate the US military in Afghanistan. The first method being used is for men to lay down in a small depression in the ground and cover themselves with a heavy wool blanket every time they hear an engine overhead — be it a helicopter or the lawn-mower whine of a drone. This technique is well documented based on visual surveillance of groups of Afghans. All they did was to prop up the edges of the blanket with twigs to let their body heat escape around the edges of the blanket. This disrupts the pattern of the human body such that there is a warm spot but it does not look anything like a person. A step up from this is to use one of the Space Blankets available on the market to do the same thing. They reflect heat right? If you have one of the heavier ones laminated to a ground cloth they can be used over and over again. In fact there is a poncho version of the space blanket that is very effective for this purpose even if you are moving about. For shelter areas you can use mass (think of adobe houses) to diffuse the heat signature such that while the whole house will glow a bit it is impossible to see inside the house. Similar methods can be used in the field. For example, when digging a fighting position always use overhead cover if possible and pack the overhead cover with dirt or stones. This, combined with the use of blankets or tarps to screen the “windows” will render most thermal imagers unable to track you. Finally there is always deception. In one exercise with a law enforcement team, we created a large number of “false” positives for them to track using small candles and Mylar balloons. Since aluminumized Mylar is the primary component in the space blankets, if you direct a small heat source onto the exterior surface, the whole surface will reflect the heat source and appear to be a large heat signature. (The aluminum can also be used to fool radar — the balloons can be strung in a line so many feet or inches apart — and as long as that distance apart is close to the wavelength of the radar beam the balloons appear to be one large solid target. I found this out many years ago when I was living very close to the largest helicopter base in the Argentine army just outside Rafael Castillo. We could float a string of balloons and get an almost immediate response …) |

Drunken Blacksmith NLI User ID: 883418 United States 02/14/2010 06:00 PM Report Abusive Post Report Copyright Violation | The best low cost method i've heard of so far consists of a 3 layered system made up of a section of thermal refractive camo netting over a heavy weight 100% wool blanket over a heavy quilted Mylar survival blanket....all 3 of these items loosely tack sewn together in a random pattern. The mylar blanket blocks most of your body heat...the thick wool blanket takes on the same temp as the surroundings...and the camo netting further disrupts the thermal sig. The original article said to cut irregular shapes or scalloping into the edge of the layered system to further conceal the shape. A set of looped handles for hands and neck allow this system to be used as a portable shelter by night and a fine Ghillie by day. The system was described as 8x8' and the user was positioned diagonally. I believe combining this system with a shallow body pit dug next to a large heat retaining boulder would pretty much defeat FLIR and would let you sleep warm and cozy all night long...fresh, rested and ready for the next days operations.

El Tiburon User ID: 28375544 United States 03/10/2013 06:31 PM Report Abusive Post Report Copyright Violation | I use a FLIR for work... I have never tried to defeat it. But I can tell you that FLIR works off line of sight and something as simple as a mirror will stop it from reading what is behind it. My first thought on defeating FLIR after reading this was MYLAR. As for overwhelming the FLIR... A trained operator can switch modes, and adjust sensitivity on the fly. So I am not sure how well that tactic would work. |
