摘要：
A novel diagnosis method for impaired subarrayed antenna arrays is proposed in this letter. The proposed method can be applied to the diagnosis of both impaired subarrays and failed elements by analyzing the impairment circumstances and using the compressing sensing -based method. The accuracy of the diagnosis results is greatly improved through an iterative reweighted l1 -norm method with the matrix techniques, even if there are many failed elements in each impaired subarrays. The analysis of numerical examples, including the diagnoisis of linear arrays and planar arrays, and the comparison with the state-of-the-art diagnosis techniques show the superiority of the proposed method for the application of diagnosis of impaired subarrayed arrays.
