A LUNEBURG LENS AS A PASSIVE REFLECTOR FOR SATELLITE COMMUNICATION*

Abstract

A specially designed Luneburg len used as a pa sive communication satellite in a stationary orbit refracts the energy incident upon it through an angle of 165 to 180 degrees, thus providing a wavefront propagating back in the general direction from which the signal came. Two formulas for the scatter pattern are eveloped -- one approximate, the other accurate. Thus, it is possible to compute values for a minimum lens size that will provide adequate signal return in a radar range. The composition of the lens must take into account the required dielectric constant distribution and yet be sufficiently light in weight. Several such compositions are discusse . (Author)
