System and method of measurement of the components of the radiation diagram of an antenna

摘要

The present invention relates to a system for measuring at least one component of the main component and the cross component of the radiation diagram of an antenna to be tested, including the antenna to be tested, and at least one antenna of the analysis is able to emit an electromagnetic wave of substantially circular polarization in the direction of the antenna to be tested according to an axis of radiation. The system comprises modules for : - turn (22), the said at least one antenna for analysis, during the emission of an electromagnetic wave of substantially circular polarization, about the axis of radiation, - for each angular position of the antenna to be tested from among a plurality of orientations, ▪ be measured (32), the amplitudes of the power received by the antenna to be tested, the electromagnetic waves emitted by the antenna of analysis, ▪ obtain (38) a maximum amplitude value and a minimum amplitude value, ▪ calculate (38), on the basis of the amplitude values of the maximum and minimum amplitude obtained, a level of amplitude of corrected power.
