INVESTIGATION OF EFFECTS OF SURFACE DEVIATIONS ON HAYSTACK ANTENNA RADIATION PATTERNS,
Abstract
The antenna of the Haystack experimental facility is of the Cassegrainian variety. At an operating frequency of 10 kmc, the reflector is about 1200 wavelengths in diameter, and it collimates the electromagnetic energy in a beam of about 0.05 degrees wide at the 3-db points. Basically the Haystack paraboloidal reflector consists of 96 doubly curved panels of two slightly different shapes attached to a complex backup structure. The outer half of the reflector is formed by 64 identical panels. The projected area of these panels in the aperture plane is a truncated sec tor approximately 28 feet long with bases about 6 and 3 feet wide, respectively. The inner half is formed by 32 panels. The projected area of these panels is also a truncated sector about 28 feet long with base widths of about 6 feet and 1 foot, respectively. (Author)
