Variation of phasing system parameters of GURT active antenna subarray in a wide scan range

In the abstract the results of transfer coefficient calculations of active antenna subarray of GURT radio telescope for all possible scan directions are presented. Also these results are supplied by measurements of signal changing with beam switching at subarray of GURT radio telescope which prove the correctness of the computations. The presented results could be useful for designing of new active antenna arrays and interpreting data obtained at present antenna arrays.
