A Two Channel Receiver at 22 GHz for Holographic Measurement of Reflector Antenna Profiles

This paper reports a two channel, coherent holography receiver for the measurement of the two dimensional reflector profile of the 30 m millimeter radio telescope at Pico Veleta, Spain. Using a phase and frequency locked Gunn oscillator as local oscillator, a path length difference of 30 μm can be m...

Summary:This paper reports a two channel, coherent holography receiver for the measurement of the two dimensional reflector profile of the 30 m millimeter radio telescope at Pico Veleta, Spain. Using a phase and frequency locked Gunn oscillator as local oscillator, a path length difference of 30 μm can be measured.
