Modern radar systems can distinguish chaff from target objects by measuring the Doppler shift; chaff quickly loses speed compared to an aircraft and thus shows a characteristic change in frequency that allows it to be filtered out. This has led to new techniques where the chaff is further illuminated by an … See more Chaff, originally called Window by the British and Düppel by the Second World War era German Luftwaffe (from the Berlin suburb where it was first developed), is a radar countermeasure in which aircraft or other targets … See more British warships in the Falklands War (1982) made heavy use of chaff. During this war, British Sea Harrier aircraft lacked their conventional chaff-dispensing mechanism. Therefore, Royal Navy engineers designed an improvised delivery system of See more While foil chaff is still used by certain aircraft, such as the Boeing B-52 Stratofortress bomber, this type is no longer manufactured.

It is designed to obscure targets on radar, so naturally it shows up in weather radar. It … WebIn most cases, the RCS is dependent on both the size of the object and the radar wavelength. Examples of other simple shapes and their RCSs are contained in Figure 2-8. For the case of the chaff dipole, it appears as if the RCS depends only upon wavelength.
