The use of two modes of oscillator operation in millimeter-wave interferometry
Abstract
An investigation of the electronic tuning characteristics of diffraction-radiation oscillators for use in millimeter-wave interferometers is presented. Two modes of oscillator operation were discovered: a mode of large electronic tuning steepness and a mode of small steepness. It is shown that different phase shifts can be obtained in the same interferometer circuit at different modulation voltages. An interferometer based on this phase-shift effect was constructed; a maximum phase shift of 30pi was recorded at a wavelength of 6 mm.
