Vatic Note: Very interesting indeed. It does not mean we will ever need this information, but it does mean we should have it in case we ever do need it. This is not as comprehensive as I would have liked, but its a direction and a beginning. Beginnings are good. They help us to direct and focus our attention on something that may well be needed in the future and being prepared is far better than being caught off guard.

We need to study what is here in this article and confirm the information through research, and if it pans out then make sure we understand it fully so we don't have to think about it when we are under the gun. Study, read, observe, and think about it. After that, then work out a plan of action and do so with your family and friends, based on all your work. Buy one of those small hand held thermal imaging items and test your work with it. Make adjustments as needed and do all of this before they begin the drone patrols.

The Afghanis and the Iranians both were able to hack into the drones and bring them down and that is also what we are going to have to learn to do if we want to stay on top of all this. The options are not acceptable. I highly recommend taking this very seriously, and especially if you plan on resisting this new fascist nazi khazar banker war against America and her people.

I would also begin identifying safe houses that could be caves or any place that they cannot find you just from knowing where you live. Once you do all this, then you can fight them on your terms, and not theirs. Also start forming local groups of friends, and neighbors and family to discuss what it is you want to do locally, but think globally.

Mossad sent 30,000 agents out last year to infiltrate local governments in various positions and those agents are using moving companies as fronts so they can attend regional meetings and have an excuse in place for their absence. Because we knew about this, we have identified one of them in our neighborhood, so they are here and working your local system to try and take it over. Mayor races, sheriff, and water boards are the most vulnerable. Make sure you know your candidates well, and if you don't, then don't vote for them.

Finally, encourage your state elected officials to set up a state militia to respond at a moments notice to actions that are against the state and its people. We are seeing states beginning that process now, and it should catch on, if we all volunteer to serve within our local area. Ponder that suggestion and do what you think is best.

How to Hide from Drones

Thermal imaging is the primary method human detection on the battlefield. Whether it be a drone, an Apache helicopter, or an individual soldier, thermal imaging is the best tool available for the job. Thermal imagers work by “seeing” heat. Everything emits thermal energy, dirt, trees, rocks, humans. Thermal imaging is so successful at detecting human beings that it poses a threat to the average citizen. Don’t get me wrong, I feel every citizen should own a thermal imager as well.

In today’s world it is becoming apparent that the average individual citizen is going to be under the prying eyes of the government, but what if Joe citizen has concerns about his privacy? I’ve been through countless forums where people are searching for an answer as to how one can hide from thermal imaging.

We are even working on a method ourselves. While I would like to be the first to develop a product to defeat thermal imaging, I feel that I should share the challenges in doing so. If I am not successful, maybe someone else will be. All of the ideas I’ve run across so far will not work; Space blankets, glass panels, mud, wet suits, none of it works.

The key to evading thermal imaging is the same as any camouflage, just with different parameters. You will not ever “disappear” from a thermal imager, just the same as you won’t disappear just by wearing Multicam or ATACS. In visible camouflage you use colors and specific patterns to do so. You have to blend in and use cover and concealment.

You wouldn’t go unnoticed wearing traditional camouflage laying down in the middle of a parking lot, you shouldn’t expect to do the same in thermal. In both examples knowing your surroundings and the characteristics of what is searching for you is the key.

In order to hide from drones and other entities using thermal imaging, you must first understand how it works. Even if you can develop a method to block your thermal signature you must also know how to use basic cover and concealment techniques, as they apply to thermal imaging.

It is not that much different that putting on optical camouflage and knowing where to hide, in fact, there are many parallels. Here are some of the specific challenges and characteristics when trying to evade of thermal imaging:

Thermal

The most obvious issue in evading thermal imaging is dealing with the heat that a human produces. It is impossible to stop the body from producing heat and it is also impossible to inexpensively contain all of the heat the body produces.

Expensive thermal cameras, such as the ones in drones and helicopters, sense the actual photons emitted from an object. Less expensive handhelds use a material that measures the differences in temperature. Either one first needs the heat from your body to reach the sensor. If your heat cannot reach the sensor, you cannot be seen.

A physical object between you in the camera, such as the roof of your house, a boulder, or a tree will stop the infrared energy from reaching the sensor. The problem is you can’t continually surround yourself with any of these objects.

You must, however, put some barrier between your heat and the camera. The above example of the space blanket will reflect heat back to your body and the imager cannot see through it, but if it touches your body the heat will transfer through the material rather quickly (like one second). If an air gap was kept between your heat and the space blanket this would slow this process down.

The Afghans have used wool blankets to mask their signatures from thermal imaging. If they hear a chopper or suspect an eye in the sky is looking for them they will drop on the ground and cover themselves with a the blanket. If the blanket starts out at ambient temperature the amount of time they will reduce their signature varies, depending on the temperature relative to their body heat.

This works because the blanket acts as an insulator. As soon as the wool begins to warm they will become visible again. I suspect this method works for mere seconds, but imagine if they had a wool blanket, a space blanket, and another wool blanket. The heat would first have to transfer through the wool.

The space blanket would reflect most of the heat back, but some would leak through. The second wool blanket would then begin to heat up compared to the surroundings. This wouldn’t work forever, by any means, but it would give the insurgent one thing; more time.

Masking your thermal signature is the biggest challenge to evading thermal imaging. There are a number of ways to obscure your thermal signature to avoid being detected:

1- Insulating your heat from the imager, such as the wool blanket. The more effective the insulation, the more time you have bought yourself.

2- Spreading your heat over a larger surface area. Your body has a finite surface area, if you can transfer your body heat to a larger object, that object will be cooler. Think of a heat sink.

3- You can vent heat to the atmosphere. The thermal imager cannot see the heat traveling through the air, at least not at the temperatures we are talking about. It would have to be directly to the atmosphere because if the heat were to heat up your cover, that would be noticeable.

4- You can mechanically trap heat.

Note, heat is also relative. If your entire environment is 98.6 degrees, you won’t disappear by any means, but the advantage of the thermal aspect will be lessened.

Note 2, all thermal cameras have what is called a dynamic range. Imagine I had a palette of 10 shades of gray available to me. As the processor of a thermal I have to assign a “color” to each temperature. The standard view would be white is hot and black is cold. If temperatures are relatively uniform, say everything the camera is seeing is between 60-70 degrees, the processor can assign a color for each degree.

If the temperatures of the objects in the cameras field of view are vastly different, say 32 degrees on the cold end and 98.6 on the warm end with lots of variations in between (say a sunny winter day) the processor can no longer assign one of the 10 colors to each degree.

It must assign a color to a range of temperatures, say 32 to 37 are “black”, 38 to 44 are dark gray and so on. This is a vast oversimplification but it does have an effect on the cameras ability to resolve your temperature. A real world example might be hiding near the top of a ridge. If someone was looking for you from below they would have to include part of the sky in the field of view. The sky is extremely cold, whereas the earth might be a hundred or more degrees warmer.

Here is a somewhat extreme example of how dynamic range can affect an image. In the image on the left our thermal cloak is towards the top, just to the right of center. In the second image, the imager includes a good portion of the cold sky causing the foreground to wash out a bit.

Emissivity
Lets say that you had some form of cloak that could mask your thermal signature for a period of time. You might think you are home free…but nothing is that simple. Not only does every object emit thermal energy, but it does so at different rates. Human skin is highly emissive, meaning energy is radiated efficiently, more energy for the thermal imager to “see”. Aluminum foil, on the other hand, has low emissivity. If both were the same temperature and you looked at them with the camera they would look vastly different. To make matters worse, as any object warms up, it also emits more energy. It can be likened to objects changing “color” with temperature. This is why emergency blankets and panes of glass won’t help you hide. While they might mask your thermal signature, they themselves will stand out compared to your surroundings. To an observer, an emergency blanket is just as out of place in thermal as it would be in visible light.
Not only do you have to reduce your thermal signature to hide from thermal imagers, but you have to match your surroundings as well. To solve the first two equations, thermal and emissivity, you must both shield the imager from your body heat and match your surroundings. So you’ve got some kind of cloak, and you’ve covered yourself in grasses or branches native to the exact area where you are hiding, you might be “invisible” to thermal.
But wait, it doesn’t end there. Somewhat like sun casts a shadow, thermal leaves a shadow. A lawn that is partially shaded from the sun will look very different in the shadows. If you were to move from the direct sunlight in the above example into the shade, you’d stand out. This is yet another reason why thermal is effective during the day. Nighttime, particularly long after sunset, offers its own challenges. After the sun sets different objects cool at different rates. If you were successful enough to create a cloak that can achieve near ambient air temperature you may now appear colder than your surroundings. Your best bet is to know what objects offer the closest temperature/emissivity match, tall grasses may cool faster than rocks, pine needles and leaves may be good options.

In this example the subject’s thermal signature is masked, but the air temperature is much colder than that of the ground. The cloaking device has taken on the air temperature causing an emissivity mis-match. While it is questionable that an operator looking for a human would give this a second look, it does stand out:
