In summary: The LIDAR knows where the asteroid's "should" be, because it knows where itself is.
Would it be possible for the LIDAR points shown to be aware of the ship's velocity and use that to anchor themselves in position. (I.e. a LIDAR scanned asteroid in front of you would be moving relative to your ship in the LIDAR screen given your ship know's these values for itself ("at all times" depending on ship computer damage, but that's above and beyond, maybe it fits into existing systems to implement it that way or not). Instead of having to track every single point and update them all to make it work, instead they are simply identified which object they are, and the entire LIDAR field perspective is shifted based on known ship movement. Only when the radar sweep gets back to an already scanned object, does it update it's position, or start to fade and slowly drop it to indicate old data. (assuming the LIDAR code has access to the raycast that penetrates objects and occlusion is then added). Alternatively it may not be necessary to keep track of objects, but tracking the object that the LIDAR point is tied to would produce a cleaner final result for players.

If you want that to make the lidar screen to act more like a game minimap instead, this is exactly the opposite of my objective of making it this way.
Also, the lidar technically doesn't have the data to do that. It doesn't know in which direction a thing is moving, it only knows if it's moving towards you or away form you, in an radial fashion.

Not the motion of the roids, but the motion of the ship, from telemetry
If a roid was, say, zipping across the screen horizontally and the ship was moving vertically, this would not let it know what it can't, just the Doppler direction as you said, and it would appear to be stationary in the field that the ship at the center of the LIDAR display is moving through
Not to make it overly mini-map like, I enjoy the active and limited display of the LIDAR
But it does seem like a data-integration a lidar display would have when you're moving through the rings at speed.
It wouldn't reveal any more information than it already obtains.
For instance, the gravimetric display is anchored to the world grid.
Just makes it easier to read and interpret when moving

Does that happen in real-life radars?

I don't know, but I imagine it would be most useful on faster moving vehicles like jets, and I don't know if I'm gonna find those details. Even then it's mostly far off detection anyway, not nearly as tight as weaving between the ring asteroids.
My thinking is just that all the information is there in the ship computer already to display the LIDAR like that, and it'd be more like other scan data, especially when so many other systems account for relative ship velocity, from autopilots to gravimetric scans.
I do suppose it would give it a less obvious sweep if it did not update most points position by much. The current sweep updating their relative position to the ship with all of them shifting.

I think this might be really confusing

Thing about moving hits on your minimap is that it might trick you into thinking that you're observing the actual movement of an object. Probably better for the system to not pretend it's modeling reality, and be clear about what it can't tell you.
