Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Radar absorbent material, or RAM, is a class of materials used in stealth technology to disguise a vehicle or structure from radar detection. A material''s absorbency at a given frequency of radar wave depends upon its composition. RAM cannot perfectly absorb radar at any frequency, but any given composition does have greater absorbancy at some frequencies than others; there is no one RAM that is suited to absorption of all radar frequencies. A common misunderstanding is that RAM makes an object invisible to radar. A radar absorbent material can significantly reduce an object''s radar cross section in specific radar frequencies, but it does not result in invisibility" on any frequency. Bad weather may contribute to deficiencies in stealth capability. A particularly disastrous example occurred during the Kosovo war, in which moisture on the surface of a F-117 Nighthawk allowed long-wavelength radar to track and shoot it down. RAM is only a part of achieving stealth."
