I was watching a youtube video about the b2 this morning. It mentions that while it’s not completely invisible to radar, it only has a cross section about the size of a bee. It says that radars have to fine tune their displays to only show larger objects or else it would be too cluttered.
I guess my question is, why can’t they tune their displays to only show objects moving faster than ~ 300 mph?

It’s not just about tuning, which you can do, but for the radar screen to show a return, the radar waves need to return.
Many stealth planes work by absorbing radar waves or reflecting them in a direction other from their origin points.
