A PHASE COMPARISON METHOD SUITABLE TO MEASURE H-MASER PERFORMANCE

R. Ambrosini

Abstract:	Very Long Baseline Interferometry is one of the modern specialized applications where phase noise instability has to characterized not only for short terms, but also over very long periods of time. This technique is utilized by radioastronomers to draw sky maps with angular resolutions of a few milliarcseconds and by geophysicists to measure continental plate motions, with precisions of a few centimeters across earth diameter distances. These types of observations are performed by networks of radiotelescope antennas, each of which needs a H-Maser frequency standards to preserve, in the receiving down conversion mixing process, the phase of the signal coming from sky radio sources.
