Abstract
A compact range system includes a feed antenna offset from the rectangular-aperture paraboloidal reflector. The reflector has blended edges and smoothed corners to reduce contamination of propagated electromagnetic plane waves by diffracted energy. The continuous, smooth surface of the reflector maximizes the purity and uniformity of the plane waves from the reflector.
