摘要：
The element failure of antenna arrays disturbs the sidelobe power level. In this paper, the problem of circular antenna array failure is mitigated using firefly algorithm (FA) by controlling the amplitude excitation of array elements. A fitness model has been developed to obtain the error between pre-failed (original) sidelobe power pattern and measured sidelobe power pattern and this function has been minimized using FA. Numerical examples of different circular array structures with element failure correction are presented to show the capability of the proposed approach.
