(Askeri) (NATO) KARIŞTIRMA REFLEKTÖRLERİ: Bir radar karşı önlem olarak ekseriya mermi kovanlarından veya roketlerden bırakılan veya uçaklardan serpilen, elektromanyetik enerjiyi yansıtmada kullanılan frekans kesici metal varak şeritlere, tellere veya metalize cam liflere verilen isim
Small strips of metal foil, usually dropped in large quantities from aircraft or balloons Chaff typically produces a radar echo which closely resembles precipitation Chaff drops once were conducted by the military in order to confuse enemy radar, but now are conducted mainly for radar testing and calibration purposes
foil in thin strips; ejected into the air as a radar countermeasure material consisting of seed coverings and small pieces of stem or leaves that have been separated from the seeds
{i} husks separated from grains; straw that has been cut up for animal feed; something worthless, refuse; teasing, joking; (Airplanes) metal scraps released from an airplane in order to disrupt signals from radar-guided weapons
Chaff is paper-like stuff that appears though the roasting process These little brown flakes are fragments of the innermost skin (the silverskin) of the coffee fruit that still cling to the beans after processing has been completed Roasting causes these bits of skin to lift off the bean
Ribbon-like pieces of metallic materials or metallized plastic which are dispensed by aircraft or ships to mask or screen other "targets" The radar reflections off the chaff may cause a tracking radar to break lock on the target The foil materials are generally cut into small pieces for which the size is dependent upon the radar interrogation frequency (approximately 1/2 wave length of the victim radar frequency) Being this length, chaff acts as a resonant dipole and reflects much of the energy back to the radar Also see rainbow, rope, stream chaff, and window
If you separate the wheat from the chaff or sort the wheat from the chaff, you decide which people or things in a group are good or important and which are not. It isn't always easy to separate the wheat from the chaff. Good-natured teasing; banter
