| Summary: | 碩士 === 淡江大學 === 電機工程學系 === 87 === The genetic algorithm is used to reconstruct the shapes of multiple perfectly conducting cylinders in free space and the single perfectly conducting cylinder in half space. Bases on the boundary condition and the measured scattered field, a set of nonlinear integral equations is derived and the imaging problem is reformulated into an optimization problem. The genetic algorithm is then employed to find out the global extreme solution of the object function. Numerical examples are given to demonstrate the capability of the inverse algorithm. Good reconstruction is obtained even when the multiple scattering between two conductors is serious. In addition, the effect of Gaussian noise on the reconstruction results is investigated.
