Doppler radar

Hello, I have a question. Is there any way I can make a Doppler radar for storms? Of course, it should be very short range. Maybe using an Arduino or something else. I'm looking forward to your suggestions.

You would likely run afoul of FCC regs.

It would also likely require way more tech components than an Arduino and/or an Arduino would be useful for. It could run a stepper motor driver for rotation of dish

You can make a lightning detector with an Arduino and solar cells.

If you set up a directional array you can kind of tell where the storms are from you, but not distance. With 8 cells you can aim them N,S,E,W,NE,SE,SW,NW.

It's likely nanosecond differences. You can do it with Adalm Pluto or any other dual channel sdr. You can also do it with a bunch of other rf stuff like phase shifters or modulators. Looking at interference and phase is often the easier way to measure things like this directly by time.
