Analysis of Mutual Shielding Effect Between the 25 m and 13 m Radio Telescope at Sheshan

Analysis of Mutual Shielding Effect Between the 25 m and 13 m Radio Telescope at Sheshan

In accordance with practical needs of a project,the mutual shielding effect between two radio antennas located within some limited area is analyzed in this paper.The concept of the externally connected sphere of an antenna in altazimuth(azimuth-elevation) mount is put forward.A calculation method vi...
