Abstract:
1. A radar reflector, comprising: a first and a second radar corner, the radar corners being formed by an essentially rectangular first flat plate and a second and a third essentially flat plate arranged perpendicular to the first plate at two perpendicular edges of the first plate and to meet said two edges of the first plate, the second and the third plates of the first radar corner being arranged to meet two different perpendicular edges of the first plate than the second and third plate of the second radar corner, wherein the second and third plate of each radar corner are rotatable at the meeting edge of the first plate from a folded position in which the plates are essentially parallel with and close to the first plate to an unfolded position in which the plates are essentially perpendicular to the first plate; and a pre-tensioned torsion spring arranged to obtain the rotation of the second and third plates from the folded position to the unfolded position.
