Research Study into the Near Earth Application of Millimeter Radio Waves as Applied to Certain Battlefield Problems

摘要

The report concerns a brief study made of the applicability of Luneberg lenses to a scanning antenna system at 35 GHz. The study showed the applicability of the approach for certain situations, but for the specific requirements of the desired application, the use of the Luneberg lens was inappropriate. The system required 35 steering of a 35 GHz pencil beam formed by a 36 in. diameter aperture. The combination of aperture size and frequency leads to a currently prohibitive materials requirement. Alternative approaches using phase shifter techniques and non-resonant slot arrays are discussed. (Author)
