I often hear about radio and micro waves being used for sensing (passive or active) and designating. IR and visible spectrum are also used which much higher resolution on things like goggles, targeting pods, rangefinders, target designators etc. What about the UV spectrum?
What little I know suggests that you could have resolution equal to visible spectrum in a smaller sensor and emitter. Wouldn’t using it at night give you pretty good signal-to-noise ratio, especially at higher altitudes? Using it during the day seems like it would effectively create a lot of fog which would limit the ability of enemies to passively detect it. Is there anything I’m missing? What else could you do with it?
