摘要： The present invention includes rolled edge compact range reflectors and reflector systems. This invention also includes machines or electronic apparatus using these aspects of the invention. The present invention also includes methods and processes for making and using these devices and systems. In a preferred embodiment, lightweight foam panels are added to the periphery of a sharp edge terminated compact range reflector. These foam panels may be shaped using simple two-dimensional cutting apparatus. The foam panels are then preferably positioned around the edge of the reflector with the planar edges of the foam pieces abutting one another so as to form a substantially continuous rounded edge to the reflector. The edge may then be shaped, filled, sanded, or coated to improve performance of the resultant reflector.
