Main Question or Discussion Point
Do blimps show up on radar? And if so, could somebody explain why? Is it the material they are made from (mylar/nylon)? Is it that their low density somehow gives an odd reflection?
Ah yes I have seen those devices, I assume you mean something like this:What's the bet that blimps are similarly equipped?
Let's say it was an unmanned aerial vehicle, I can imagine the props being metal, the batteries being dense but apart from that nothing metal that could reflect its true size (other than the envelope, if that does indeed reflect radar). The electronics/cockpit, passenger area can all be ignored in this case.would also depend on what else on the blimp was made of metal.... the cockpit, passenger area, the engines etc....
There's sure to be some reflections, but they wouldnt really give a good indication of the full size.
I would imagine so, however would it be possible to spot the rain wet blimps radar reflection if it was also raining all around the blimp? Wouldn't the signal be hidden by the rain noise?On another thought train tho .....
rain ... which is of course not metallic, reflects radar quiet easily. Us amateur radio operators use a number of microwave radio frequencies to do what is called rainscatter communications.
One wonders if a rain wet blimp would reflect radar easier/more efficiently than a dry one ?
