Out of curiosity, I did some research on Thermal imaging and found this:

If you are on bare clay or gravel (38-40) and are worried about aerial observation, dig in. Cover yourself with almost anything sufficiently rigid and then cover it with at least a thin but full layer of the local "dirt". This will match the E's. Once the moisture of the new cover layer equals the moisture of the surface around you (evaporative cooling), you will be in decent shape IR wise. Remember that these low E materials have a high
Reflectivity, so block your own IR from getting out from
under the cover. If there is a chance your body heat will affect the top surface of the dirt cover, use insulating material between you and the bottom of the "roof" to keep it the same temp as the ground around you. Foam board or sleeping bags will do that. The most critical times of day for this hide would be as the sun changes, because rapid heating/cooling of a thin layer of dirt will show up compared to the slower heating/cooling of the
intact soil masses. If you can set up in a shaded spot
where this will not occur, you should be in decent shape. If there is no shade, make the cover layer thick to create a heat sink approaching that of the surroundings.
