Application of Cultural Algorithms in the Pattern Synthesis of Array Antenna

A cultural algorithm is applied to solve the problem of array antenna pattern synthesis with the target of the side-lobe reduction.Then an implementation of real-code cultural algorithms is produced.Cultural algorithms are dual inheritance systems,which are different from the others.Because of the feature,the search process is guided by using knowledge abstained from the process of solving problem,which can produce substantial performance improvements.The results of computer simulation verify the efficiency of the proposed method,which can satisfy requirements about low side lobe with high convergence rate.
