摘要：
A time-domain numerical method to achieve reconstruction of conductor cylinders was considered in this paper. The obstacle is characterized by the uneven distribution points instead of the usual shape function. The electric field is solved by Time-Domain Finite Element Method (TD-FEM), and Genetic Algorithm (GA) is adopted as the optimization method. Norm of the uneven distribution point's radius vector is set as the independent variables for the fitness function. The objective function is the ratio of the total error between the scattering electric field of the obstacle and computed scattering electric field to the sum of norm of the scattering electric field of the obstacle. Imaging results is achieved by minimize the objective function through the genetic algorithm.
