Surely Weather Radar can be picked up on the ground. Otherwise I would not get ground returns when I tilt it down.
Normally I would tilt it so that the ground reurns are just at the edge of the selected range on my display - say 40 miles for example.
The radar will be receiving signal from much further away than 40 miles. If I just select 80miles on radar range without adjusting tilt then 40-80 miles will just show ground returns.
I believe military radars can i.d. planes by comparing spool speeds inside target aircraft engines so I expect detecting a wx radar would be straightforward. Knowing that it not an enemy aircraft sending psudo Wx radar signals might be a bit trickier.
