Personally I don't believe being hunted by people with thermal imaging equipment would be much of an issue, however, I get the fun element WnC said as well.
On a much more serious note, the idea of a thermal poncho is REALLY appealing! Although an issue of sweat and thus dampness may counteract the idea of the poncho, to stay dry.
WnC showed me some awesome thermal bivis the other day. I don't have a clue what thread, but they were made by "Adventure Medical Kits" (I think that was their company name). They were called "Stay in the Outdoors Longer" or something like that. Really compact and useful! I'll be adding one to my sleeping system.
You could use the thermal tarp as a cross between a bivi bag & a bivi tarp. Ie, don't seal the ends up and maybe a short pole or rucksack at the head end. This will allow a throughflow of air and whilst not being quite as thermally efficient, may still produce good thermal properties. it would need a trial to find out. I have slept under offcuts of carpet in a house with no gable end wall & open to sub zero temps. My sleeping bag had gone walkies. The carpet proved good enough to retain my body heat whilst still fully clothed. This insulated tarp idea could turn out to be quite useful. I shall have to try it out sometime soon.
About the thermal imaging, I do agree you are unlikely to be "hunted" by anyone with this tech, but I do think it is feasible that forces aircraft, ie heli's or other may be fitted with this gear and could pick you out by chance as they scan areas for whatever reason. They would not know you were a civilian/prepper and so may take an interest in I.D.ing you as a potential threat. This is more likely in an outdoors/countryside scenario and again, I do not think the probability is high - just that it could be a possibility.. the hunting type scenario I am not suggesting at all.
SD, how are you going to detect or jam PIR's?
