Superheterodyne receiver for two microwave signals with two opposite circular polarizations

摘要

Device for simultaneous reception of waves circularly polarised in opposite senses with waveguide means transforming the circularly polarised waves into linearly polarised waves of opposing senses or differing directions, and, for each linearly polarised wave, a circuit (231, 241) of the superheterodyne type. The two circuits (231, 241) comprise a common local oscillator (25). IMAGE
