Comparative Study of Linear Array Pattern Synthesis Using Iterative Fourier Transform Genetic Algorithm

摘要

This paper presents Iterative Fourier Technique (IFT) and Genetic Algorithm (GA) for the synthesis of low Side lobe patterns for linear array with uniform element spacing. A comparative study is done with Array Element failure is introduced at various location of linear array in distributed and concentrated form. Quantitative results are presented to show effectiveness of the algorithms for failure correction in terms of pattern recovery. The MATLAB simulation results are presented for 50 and 80 elements arranged in regular grid for antenna sum pattern.
