ABSTRACT:
A low sidelobe reflector for improving the test zone performance of compact ranges by shaping the edge serrations of the range reflector. The serrations provide a means for synthesizing desired illumination function tapers at the transition region near the edge of a reflector to provide low edge diffraction. Serrations with length greater than ten wavelengths and with a flower petal shape produce the least diffraction of energy into the quiet zone.
