Radartelts

Radartelts is a term sometimes used colloquially to refer to radar reflectors, specifically those deployed to enhance the detection of small or stealthy objects by radar systems. These devices are designed to passively reflect radar signals back towards the source, thereby increasing the object's radar cross-section. They are particularly useful for improving the visibility of non-metallic objects, such as buoys, marine debris, or certain types of aircraft. The shape and material of a radartelt are optimized to reflect radar waves efficiently across a specific frequency range. Common designs include corner reflectors, which consist of three mutually perpendicular metallic plates, and Luneberg lenses, which are spherical reflectors that focus incoming radar energy. The effectiveness of a radartelt depends on its size, shape, and the wavelength of the radar it is intended to interact with. In some contexts, the term might also be loosely applied to active radar decoys, which emit their own radar signals to mimic a target, though this is a more complex technology.
