how does RCS work. I saw that the F22 has RCS similar to a bumblebee so how does that work. Does it mean that it is as hard as finding a bumblebee

I take a bright flashlight and shine it at a wall. First it’s a vantage black wall and it seems like nothing happens, then it’s a standard beige wall and it’s obvious where the light is, then it’s a mirror and the bright light is almost blinding.
Then I shine it at another wall that is all mirrors. But this one changes in angles some flat at me, some angled up, some angled in all sorts of crazy shapes. Some of these will reflect a lot of light at me and some will send it flying every which way.
Reducing the radar cross section is rather similar. You use coatings, specific geometry (think the F117 or the hidden tail fins of the F22), and making sure everything is incredibly smooth. The end goal is to make it so as little of the radar wave (light in my above example) is reflected back to the radar. If you absorb it or send it somewhere else, the system doesn’t know because nothing came back, the same as the wave going into the sky and not hitting anything.
