Escape & Evade Thermal Imaging

In a SHTF scenario, organizations or individuals might have force multiplier technology like thermal imaging.  A key component which should be part of any survival kit can easily conceal your body heat and allow you to escape detection.

Emergency Blankets

Emergency blankets work to keep you warm by reflecting body heat back towards the individual.  It would make sense that this life saving technology can also be used to prevent body heat from being detected via thermal imaging.  Take a look at the below video to see how effective it can be:

A key note about this video is that some of the emergency blanket configurations are pressed up against the individual’s body.  You will get much better results if you have the blanket propped up as a tent/tarp rather than wearing it.  Also, emergency blankets come in all different materials and thicknesses.  While the cheap/thin blankets might provide some thermal imaging prevention, the thicker/sturdier versions (mentioned below) will offer much better concealment.

    If you are using the shiny side of a space blanket toward you to keep your IR from getting out, remember that the backside of it is probably not a good E match to the surroundings and it will heat/cool a lot differently than most natural things around you. If you are trying to put the shiny side out angled down to reflect the IR of the terrain right in front of you, there would be a 10% reduction in the reflection, more if it casts a shadow. If the shiny side is out and up, it will reflect the cold of outer space (or the heat of the sun) – and it is going to look REALLY weird to visual and starlight in EITHER case!
