Abstract

In this paper, the results of active antenna diagnostics using “compressed sensing” approach have been presented. The optimal parameters of the chosen diagnostics’ method have been determined and influence of antenna under test thermal instabilities on the diagnostics results has been analyzed. The theoretical measurement matrix has been calculated for a near-field measurement case. The theoretical and experimentally acquired measurement matrices have been compared, showing a good agreement between them. The conclusions about the amplitude directional pattern influence on the diagnostics results have been drawn. The influence of regularization parameter on the result of diagnostics, especially in presence of thermal instability, has been analyzed. Recommendations for selection of regularization parameter have been given.
