The property of a material that relates to how well that material radiates infrared energy when compared to ‘perfect emitter’ at the same temperature is ‘emissivity’. This is extremely important for the thermographer to know when inspecting target components. Martin Robinson, CEO of IRISS explains and demonstrates why it is imperative to know emissivity.

I hope they have assessed how easy it is to shield a drone against the attack. Hopefully the shielding would add too much weight.
