night vision, which uses infrared light to illuminate a scene that’s not visible to the naked eye.
I want to see that satellite with it's massive IR device. Ha!
That's kinda what SAR sats do. They're using radio waves but they illuminate swaths of the planet with a big dish/array and then look at the reflections. LIDAR sats too.
