Abstract

The theoretical foundations of testing antenna parameters and characteristics in the far radiation field are presented. A two-beam model of radio wave propagation was used, including a direct wave and a wave reflected from the earth's surface. This model meets the conditions for carrying out measurements on a signals training areas or in an anechoic chamber. It is shown that for a given distance between the antennas, it is necessary to control the dimensions of the aperture  transmitting and receiving antennas for the compliance with the maximum permissible values. Formulas for determining the permissible dimensions of the antenna aperture are obtained. The influence of the antenna hanging heights on the measurement accuracy was also investigated. Recommendations for reducing the level of electromagnetic waves reflected from the earth's surface are given.
