A genetic algorithm with an adaptive chromosome structure is proposed to reconstruct the electrical parameters of a multilayered radome of finite size. In order to avoid the complicated scattering from the edges of the radome, a Gaussian beam is used to illuminate the central area of the radome surface. An adaptive chromosome structure technique is used to obtain a high convergence rate through adjusting the searching range for each parameter. Numerical performance using this technique is compared with that of the conventional genetic algorithm. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 25: 323–327, 2000.
