Abstract

This paper presents a computational approach to reconstruct the shape of a perfectly conducting cylinder illuminated by TE wave. Base on the boundary condition and the measured scattered field, we have derived a set of nonlinear integral equations and reformulated the imaging problem into an optimum one. By using the genetic algorithm, the shape of the object can be reconstructed. The genetic algorithm is always converge to a global extreme solution no matter what the initial estimate is. Numerical results are given to demonstrate that even the initial guess is far away from the exact one, good reconstruction has been obtained. In such a case, calculus-based method often become trapped in local extreme.
