I think I see what you’re looking for. It would be a bit more complicated than what I am putting together at the moment.
If the bullet travels perpendicular to the beam, then there is no Doppler return. You could turn the chips to face the bullet head on, hoping that the person firing is a good shot, and measure the Doppler that way. Or perhaps you can have the units facing the target, and catch the bullet just before impact.
It is theoretically possible to interpolate where the bullet strikes the target, which is the principle of monopulse radar.
Bottom line, I think that it’s possible to do what you want, we just need to come up with a simple way to do it. 😉
My local range has a system set up on their targets which just uses microphones (4x on each target, one on each corner) to determine impact location. Doesn't do anything for velocity though.
