How does stealth work? Why can’t we just tune radars to look for very fast ‘bumblebees’?

588 viewsOtherPhysics

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?

Asking a radar to look for a fast bumblebee is like asking a person to find a moving white dot in a bunch of TV static. It is incredibly difficult to identify anything out when there’s a ton of signals and noise constantly appearing and disappearing at the same intensity as the thing you’re looking for, much less figure out how fast that thing is going.
