Cluster reflector for targets with weak reflections - consists of six corner reflectors with their axes of symmetry at specified angles to each other

摘要

The cluster reflector improves the radar visibility of reflecting targets moving in three dimensions such as aircraft or ships. The reflector consists of a number of corner reflectors. Six corner reflectors (1) with three perpendicular to each others surfaces form together a cluster reflector. The axis of symmetry (2) of each corner reflector forms with the axis of symmetry of an adjacent reflector an azimuth angle of 60 deg. and with axis of rotation of the cluster reflector a vertical angle of 90 deg. The corner apertures are so oriented in azimuth directions that when the axis of rotationis vertical, aperture peaks (4) point alternately upwards and downwards.
