window

window
i. Any device introduced into the atmosphere to produce an appreciable radar echo, usually for tracking some airborne device or tracing the wind.
ii. A World War II code name for a type of radar-jamming device employed to confuse the operators of enemy radars (also referred to by the code names of rope, chaff, and clutter). One type of window consists of packages containing thousands of small strips of paper-backed tin-foil, which may be dropped from aircraft and balloons, ejected from rockets, and carried within balloons. The packages burst open upon ejection, scattering the tinfoil widely and producing a radar echo, which looks like a small shower or a tight formation of aircraft on plan-position-indicator scopes. The same as chaff.
iii. A specific period of time during which there is an opportunity, such as a weather window.
