经验方法和修正的Feltcher算法选取阻尼因子的介质重构比较
A Comparison of the Reconstruction Result Between the Empirical Method and the Modified Feltcher Method in Selecting Damping Factor
【摘要】 对在 TM 简谐波照射下的目标重构,从散射的积分方程出发,采用矩量法离散该积分方程,对所得的非线性方程组采用 L-M 方法求解,数值比较了对阻尼因子选取采用修正的 Feltcher 算法和经验方法重构的结果。
【Abstract】 The nonlinear coupled-equations is formed by the method of the moment (MOM) based on scattered integral equation and is solved by evenberg-Marquardt method. The reconstruction result is compared between the empirical method and the modified Feltcher method in selecting damping factor.
