Pericles asked a question in the counter-UAV discussion on Sipsey Street post I mentioned previously.
Need the militia equivalent of this:
A few smart guys should be able to replicate 1950s technology at a reasonable cost.
Ask and ye shall receive. Team Brainiac over at MIT came up with a coffee can radar. For $240 they created a High Resolution X-Band Linear Rail SAR Imaging System.
I wonder if it can spot a UAV…
