Efficient approach to analyze the dual-reflector antenna system with defocused feeds

Abstract

A time-saving reflection point locating technique based on the geometrical optics approximation is proposed. The technique provides an efficient evaluation of a Cassegrain or Gregorian antenna system. For comparison, all the reflection points are calculated with the proposed technique and W.V. Rusch's approach (1979). Patterns calculated by these two… (More)
