Phased antenna array reconstructive diagnostics using small number of measurements

In this paper a modification of a “Compressed Sensing”-based (CS) diagnostics method is presented. The reconstructive diagnostics is carried out in two steps. First, a preliminary diagnostics using CS approach is performed to determine the positions of potentially defect elements. Second, the additional measurements are conducted to improve the diagnostics accuracy. This approach combines the advantages of CS-based and element-wise diagnostics.
