Array Failure Correction Using Different Optimization Techniques

Abstract

An approach to synthesize array antenna is proposed on the context of detecting single and multiple fault in any array of elements, analysis of radiation pattern degradation because of the fault, and finding a recovery solution of the array, the recovered excitations fed to the array of healthy elements to get the radiation pattern close to the original form , For this a self-recoverable antenna array is created (SRA). The SRA concept and realization of the different recovery algorithms challenges are discussed. The resulting radiation pattern generated from the new excitation is found by three optimizing algorithm and compared.
