If people are lost in the woods, or in an avalanche, why don't the search teams use heat sensing radar?

I mean, FBI and stuff use this stuff to see in to buildings.. I've seen it on TV, this isn't Hollywood based..

Wouldn't you think that since snow has no heat, someone in the snow would be detected easily? Or at night when a hiker is lost..

I know there are a lot of animals, but a human heat form is easier to tell from anything else.. I guess it would sort of be like a real life 'Where's Waldo?'

Or am I wrong.. they do use heat detectors..

    I guess the heat sensing radar is used in confined areas not big as the woods. If it use in the woods, then it need to cover a vast areas and it certain cost a lot man power and money to do that. Don't you think?
