Why?
Let us assume that it's possible to build, say, a radar system that can detect on object as small as a bullet. From that point, it's fairly straightforward to conceive of a way to distinguish incoming bullets from bugs, thrown rocks, etc. Simply set parameters to measure the Doppler shift of the return, and only react to objects incoming above a critical velocity.
So unless thrown rocks and insects can reach speeds of 2000 fps, false alarms are not a problem.
This is, of course, highly theoretical. I have only rudimentary knowledge of the capabilities of radar, and I acknowledge that there's a big difference between conceptualizing something and actually making it work in real life.
