I'm surprised we don't basically just have a rectangle at a 5 or 10 degree angle that's 100m wide to "sweep" the sky and deflect debris to a faster burnup trajectory. I guess keeping it stable from impacts would be annoying, but you could put a solar array on the back of it and use ion engines to stabilize it.

It might not even have to be that big considering how good mission control people are at calculating trajectories.

High-speed impacts are likely to generate smaller, harder-to-track bits of debris at less predictable angles. Check out the link in klohto's comment.
