Estimation of an error on phase progression measurement on microwave line-of-sight link

In the presented paper the principle of work of the equipment for microwave propagation investigations is considered. The equipment lets to carry out the measurements of fluctuation of amplitude, phase progression of microwave. The equipment realizes homodyne method of measurements. In a paper there are discussed the problems of influence of fluctuations of initial phase of microwave oscillations on a phase errors of measurements. In a paper there were shown the ways of elimination of an error of measurements due to fluctuation of initial phase of microwave.
