Abstract

This paper presents the method of determination of the amplitude and plane distribution in antenna plane aperture. This method is based on homodyne one, where the initial microwave oscillation is heterodyne one. The mobile probe unit consists of proper antenna probe and reflecting controlled phase shifter. The initial microwave oscillation is shifted on low frequency with reflecting controlled phase shifter. The initial phase and frequency of microwave oscillations are eliminated. Low frequency feeder with arbitrary phase stability is used to carry the low frequency oscillations to mobile probe unit. The initial phase of low frequency oscillation is transferred on microwave.
