A corner reflector is a type of passive jamming and camouflage device designed to counter radar detection; it consists of three mutually perpendicular metal plates (or mesh panels) forming a solid angle.
Corner reflectors can be classified according to various criteria: By panel shape (square, triangular, fan-shaped, hybrid, etc.); by panel material (metal plate, metal mesh, metallized film, etc.); by structural design (permanent, foldable, modular/assembled, hybrid, inflatable, etc.); by the number of quadrants (single-corner, 4-corner, or 8-corner types); and by edge length (standardized sizes of 50 cm, 75 cm, 120 cm, and 150 cm), with edge lengths typically ranging from 10 to 80 times the wavelength.
In my country, the naming convention for corner reflectors primarily uses a combination of Hanyu Pinyin letters and Arabic numerals, arranged in the order of panel shape, structural design, number of quadrants, and edge length (in centimeters). For example, the FZ4120 corner reflector denotes a square, modular, 4-corner unit with an edge length of 120 cm.
