Failure Correction of Linear Antenna Array using Grey Wolf Optimization

The work concerns the problem of monitoring linear antenna arrays using a new scheme denoted as grey wolf optimization (GWO) algorithm. When a strange event (fault) affects an antenna array, the radiation diagram changes and important deviation from the preferred pattern can occur. In this work, re-adjusted of the amplitude and phase distribution of the lasting working elements in a faulty array is considered. This latter can improve the side lobe levels (SLL) and also keep the directivity. The main point of using the GWO technique is its ease of implementation and a high performance computational technique. To assess the strength of this new scheme, different types of failures as case studies were performed. Simulation results evidently have shown the efficiency of the proposed algorithm to correct the failure correction of linear antenna arrays.
