No. This is about IR mapping of the planetary surface. However it is quite an interesting technique. I found this link, which explains in more detail: http://tes.asu.edu/about/technique/what1/index.html They look at the IR emission spectrum from individual small areas of the surface and subtract from it the black body radiation envelope appropriate for that temperature. What remains is a characteristic difference spectrum for the minerals exposed at the surface, at that location. It's a clever way of doing geology from orbit! But it won't have anything to do with the IR emissions of the whole planet into space, still less anything to do with radio waves.
