Genetic Algorithm (GA) Based Techniques for 2D Microwave Inverse Scattering

This paper deals with inverse scattering techniques based on genetic algorithms (GAs), and is devoted to microwave imaging and microwave nondestructive testing and evaluation (NDT/NDE). In the framework of near-field spatial-domain algorithms, a brief overview of current trends and future developments of the research work is given. Numerical results of selected simulations, modeling realistic geometries, are presented in order to assess the effectiveness of the proposed optimization methodology. Finally, a discussion fixes some guidelines and points out the open problems to be addressed in order to enlarge the application area of GA-based inverse scattering techniques.
