corner reflector

A corner reflector is an antenna reflector that reflects electromagnetic waves in such a way that the reflected waves always leave the reflector

in the same direction in which they hit it. The electromagnetic waves are thus reflected in the direction of their point of origin. They serve as radar targets or marker points. Corner reflectors consist of three reflecting surfaces mounted at right angles to each other. In the case of vertically or horizontally polarized waves, two reflection surfaces at right angles to each other are also sufficient. In principle, the incident electromagnetic waves are reflected by the reflecting surface they hit at the angle corresponding to the angle of incidence

reflector The same happens at the second reflection surface. The sum of all reflection angles is thus always 180 degrees, which means that the waves leave the reflector in the same direction in which they hit it.
