| 摘要 | Through-wall imaging (TWI) is proposed to reconstruct the shape of a metallic cylinder. The ability of dynamic differential evolution (DDE) stochastic searching algorithm for shape reconstruction of 2D conducting targets hidden behind a homogeneous building wall is demonstrated by using simulated backscattered fields. After an integral formulation, a discretisation using the method of moment is applied. The TWI problem is recast as a nonlinear optimisation problem with an objective function (OF) defined by the norm of a difference between the measured and calculated scattered electric field. Thus, the shape of metallic cylinder can be obtained by minimising the OF. Simulations show that DDE can successfully reconstruct the TWI for a metallic cylinder. In addition, the effect of Gaussian noise on the reconstruction is investigated. |
