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?

Radar detection is subject to uncertainty. The more you tune to focus on velocity the less certain you can be of position, and vice versa. So, narrowing position to “bee-size” would make it difficult to distinguish between a fast or slow bee.
