Hybrid Sparse Reconstruction-Method of Moments for Diagnosis of Wire Antenna Arrays.

In this work, sparse reconstruction is hybridized with method of moments (MoM) for diagnosis of wire antenna arrays. In the hybrid method, excitation voltages of array under diagnosis are related to near field observations through integral equations (IEs), and IEs are transformed into matrix equations by MoM. Sparse reconstruction is then used to solve excitation voltages of array under diagnosis. Finally, locations of failing elements are found by the solved excitation voltages. The hybrid method models mutual coupling effect by MoM, and it achieves higher diagnosis reliability than sparse reconstruction without mutual coupling consideration. Simulation results are presented to show the validity and advantages of the hybrid method. [ABSTRACT FROM AUTHOR]
