Adaptive genetic algorithm for damaged beam pattern re-synthesis of active phased array

This paper proposes a method for re-synthesizing the optimal beam pattern from the damaged beam pattern using adaptive genetic algorithm based on a beam pattern mask. The resynthesized beam pattern was produced by a computer simulation. It showed well-matched results within the desired beam pattern mask. The proposed method allows increased calculation speed with improved accuracy. In this study, the proposed method is implemented with the appropriate specifications for realistic situations. We assume that the amplitude and phase distributions were quantized to 6 bits for computer simulations. The Chebyshev beam patterns are examined utilizing the proposed algorithm. Section II presents details of the proposed adaptive genetic algorithm; Section III provides the results and discussions of the proposed algorithm; and Section V gives conclusions.
