摘要：

A time-domain numerical method to achieve reconstruction of conductor cylinders was considered in this paper. And the obstacle is characterized by the discrete points. The electric field and magnetic field on the extrapolated boundary are solved by Time-Domain Finite Element Method (TD-FEM), and than the far-field value is obtained from it. Genetic Algorithm (GA) and real differential evolution strategy are adopted as the. optimization method. Norm of the discrete point's radius vector is set as the independent variables for the fitness function. The perimeter range is got by analyzing the far-field value. Imaging results is achieved by minimize the objective function through the genetic algorithm and real differential evolution strategy (RDE).
