Mobile and fixed systems like https://en.wikipedia.org/wiki/Sea-based_X-band_Radar https://en.wikipedia.org/wiki/Sea-based_X-band_Radar exist around the US and are reported to be able to pickup baseball sized objects from the other side of the continent (and that's what they claimed a decade ago before the upgrades).
They're just typically not used with such precision because of the sheer amount of false positives they'd generate and how little concern there typically is about something so small.
- ben7799 4y agoI've seen that thing in Pearl Harbor.. pretty amazing. Navy guys claimed it could track a baseball in orbit.
- mywittyname 4y agoI suspect objects "in orbit" are some of the easiest objects to track. Once you have a few data points, you can pretty much calculate where it will be at any given point in time. It takes a lot of energy to meaningfully alter the course of an orbiting baseball, so much so that any attempt to do so would probably result in the operator now successfully tracking a debris cloud that used to be in the form of a baseball.
