A Closer Look at Stealth, Part 3: Radar-Absorbent Material
Stealth is usually associated with shaping, but materials play an important role in the technology as well. Radar-absorbent materials (RAM) and other low-observable material techniques are vital for suppression of radar returns from engines and antenna cavities as well as suppressing returns from edge diffraction and surface waves. In the third part of Aviation Week’s State of Stealth series, we turn our attention to this material side of stealth technology and present this gallery as a supplement highlighting some of the past and present material approaches to reducing radar cross-section.
