| Summary: | 碩士 === 淡江大學 === 電機工程學系碩士班 === 103 === This thesis presents an inverse scattering problem for recovering the shape of Through-Wall conducting cylinders behind the wall by self-adaptive dynamic differential evolution (SADDE). The Through-Wall conducting cylinders of unknown shapes are behind the wall and illuminated by the transverse electric (TE) plane wave from another space.
Based on the boundary condition and the measured scattered field, the nonlinear integral equation is derived and the imaging problem is reformulated into optimization problem. The self-adaptive dynamic differential evolution is employed to find out the global extreme solution of the object function. Numerical results show that the shape of the conductors can be well reconstructed.
