The features of reception of polarized radio emission on spaced and large aperture antenna arrays are investigated. The most complete, answering the present state model of the radio telescope of УТР- 2 is built. New effective methodology for calibration of radio telescopes that are built on the basis of phased antenna arrays is offered. The effective methodology is worked out on the exposure of reasons of failures or deviations from the basic value of descriptions of any of the systems of radio telescope of УТР- 2. The transmitter, control system and active receiving antennae for the system for measuring ground parameters are investigated, built and tested. System for the input control of antenna amplifiers and system for measuring the dynamic spectrum of non-linear multiport are investigated, built and tested. Product Description popup.authors Є.Р.
