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?

Partial and incomplete answer, but at an ELI5 level – it’s really hard to tell if that bumblebee is moving really fast, or if you’re just seeing different bumblebees.
