Stealth Technology

I know that stealth was designed with the angles so that it would deflect radar waves instead of reflecting them due to some Diffraction mathematics and radar absorbing materials, but how good is it? Does the angle at which the radar beams hit the plane matter. After speaking to others on the web, I found the answer. Stealth technology has jumped in leaps and bounds since it was first conceived. Now our stealth technology is very good as we have radar absorbing paint, heat exchangers to cool exhaust temperature from engine (think heat seekers missiles) composite materials that reduce radar reflectivity. The use of angles and multiple surfaces has benefited stealth technology greatly as they need a surface to bounce off, I belive most radar has a angle of . 4 degrees difference to measure or detect objects. We have radar jammers in use, and different ways to throw off the enemy, such as the Northrop Grumman has a gaff technology that will fire strips of tinfoil with little explosives in the air to confuse incoming missiles. The earliest stealth technology was to paint the bottom of the plane white for day time flying and painting them black for night time flying.

    Radar, and all other energy (like light), needs to be reflected off of something and back to you to be seen/detected. If the angle isn't right, it will be bounced in a direction other than yours. Also, like you said, diffraction and radar absorption play key roles. The ATF-23 (Loser in the F22/F23 gov't contract competition) had a radar signature about the size of a pigeon.
