An Improved Inversion Model for Two-Dimensional Microwave Imaging

An improved scattering field measurement model is adopted to calculate the scattering field under the condition of the Born Approximation. The relative dielectric constant of the object to be measured is discretized through the integral equation of electromagnetic field. DE algorithm is used to solve the minimum fitness function for imaging. Simulation results show that the improved model can effectively enhance the accuracy of the dielectric constant.
