Is three feet under enough to mask the bunker from thermal imaging monitors?
Short answer: no
, because the technology is good enough to detect structure thousands of feet underground.
There are a number of issues, of which heat is only one. For heat imaging, the solution is to avoid square shapes. There are natural variances in the
abillity of soil to retain heat. Anyone looking at an imaging map is going to be looking for straignt lines. So don't give them any.
The first step is going to be to buy a bunch of space blankets
and spread them out on five out
of six sides of your construction, leaving the ground unshielded so your bunker does not become an oven. This will not only block heat, it will also
tend to block EM emissions from computers, refridgerators, and other electronics, though doing so may make you stand out even more strongly to
ground penetrating radar
. To avoid that, you might consider a top layer of
foam. Next, dig out the area surrounding your bunker in strange,
random shapes of varying depths, and with a scattering of oddly shaped pockets. Fill the entire area in with concrete, but do it in multiples stages,
and rearrange the surface with a shovel as it dries. You don't want a reflective flat surface of concrete. It should be heavily contoured. Cover with
varying depths of dirt of top. The overall goal here is not to prevent them from seeing you. They will. But you want them to see something that blends
in naturally with the surrounding terrain; something that looks natural variances of soil density and rocks instead of a bunker.
The weakest point is likely to be your entrance, to which there are a number of solutions, but I would suggest building a sideways tunnel entrance
rather than a straight-down-from-top entrance. Keep in mind that the flat edges of the tunnel will be just as visible as the flat edges of the bunker.
Extend your varying-depth-concrete layer above the length of your entry tunnel.
Another thing to consider...how are you getting to your bunker? WIll you be driving? All of the above is going to be fairly irrelevant if you have a
pair of SUVs parked a dozen yards from the entrance. If you have the space, you might consider building the place to accomodate vehicles. Make your
entrance big enough to drive them in, and store them inside.
what would be the best bet to secure electronics in the bunker from EMP interference?
The space blankets mentioned above should provide some protection from EM pulses, but if you use steel shipping crates, your entire bunker will
basically be a huge Faraday cage
I am having trouble thinking about how to go about the roof if I go this route. Any ideas?
I'm not sure I understand what the problem is. If I understand your description, you'll have a wooden section to your walls...what's stopping you
from simply anchoring ceiling support beams directly to it?
I figured the ATS crowd could help and you all delivered. Appreciated.
Happy to help.
