The most common types are the Yagi antenna, the log-periodic antenna, and the corner reflector antenna, which are frequently combined and commercially sold as residential TV antennas.
22.
A "'corner reflector "'is a retroreflector consisting of three mutually perpendicular, intersecting flat surfaces, which reflects waves back directly towards the source, but translated.
23.
A simple corner reflector consists of three conducting sheet metal or screen surfaces at 90?angles to each other, attached to one another at the edges, forming a " corner ".
24.
:: : : They also reduce the radar signature of the aircraft by avoiding the right angle between the horizontal and vertical fins that acts like a corner reflector for the radar.
25.
Sazhen-S can measure the slant range to space craft fitted with corner reflectors which are in orbits with altitudes between and ( between low earth orbit and above geosynchronous orbit ).
26.
Why are V-tails so stealthy, since when top of the aircraft faces the radar it forms a right angle or corner reflector ?-- Whale 05 : 05, 30 June 2010 ( UTC)

Scientific instruments included a soil mechanics tester, m ( 8 ft 2 in ) boom, a radiometer, a photodetector ( Rubin-1 ) for laser detection experiments, and a French-supplied laser corner reflector.
28.
The most efficient way to reflect radar waves back to the emitting radar is with orthogonal metal plates, forming a corner reflector consisting of either a dihedral ( two plates ) or a trihedral ( three orthogonal plates ).
29.
They developed an optical system that allowed real images to float in space, to appear and disappear in an environment made up of a wall array of 6-inch corner reflectors in which the visitors saw multiple images of themselves.

Corner reflectors are placed on the vessel's masts at a height of at least 4.6 meters ( 15 feet ) above sea level ( giving them an approximate minimum horizon distance of 8 kilometers or 4.5 nautical miles ).
