Dual-shaped reflector design
Abstract
Software for dual shaped reflector synthesis was upgraded to more rapidly and automatically generate an entire 3-dimensional, 2-reflector system as opposed to arbitrarily chosen profiles. A physical optics/physical optics analysis program was developed which used raw data without interpolation and converts these data into triangular facets that are appropriately ordered and thinned. A series of profiles was developed. These profiles are not rotationally symmetric nor a portion of a parent circularly symmetric geometry. They should provide -30 dB sidelobes for the feed located at the focus. The eometry permits one beam for feed in a multiple beam configuration. The geometric theory of diffraction was used to test the geometry.
