Abstract

The flexible radar reflector is of the type comprising light adjacent tetrahedral rectangles having a common peak or summit. The bases of the tetrahedrals form a regular octagon whose centre is the common peak or summit. The reflector comprises sails or wings with three squares made from flexible and reflecting material attached. These are cut along a semidiagonal i.e. a line joining the centre of the square to one of the corners of the square. Alternatively they may be cut along a line joining the centre of the square to one of its sides. These components are assembled to form a spiral and the reflector is deployed using a rigid frame of rods.
