A linear antenna array failure detection using Bat Algorithm

The element failure detection of antenna arrays is a practical issue in communication field. The sidelobe power level increases to an unacceptable level due to element failure conditions. In this paper, the problem of antenna array failure detection has been solved using Bat Algorithm (BA). A fitness function has been developed to obtain the error between degraded sidelobe pattern and estimated sidelobe pattern and this function has been optimized using BA. Different numerical examples of failed elements detection are presented to show the capability of this proposed approach.
