摘要： 该文提出了一种能够加速时域玻恩这代法收敛的频率补偿技术,并把频率补偿技术应用于时域玻恩这代法求解二维无耗介质体的剖面重建.数值结果表明频率补偿技术能有效地提高时域玻恩迭代法的收敛速度.

Abstract: In this paper, we presnet a new method for improving Born iterative method——the frequency coniensation technique. The frequency compensation technique is used to solve nonlinear inverse scattering problem for two-dimensional lossless dielectric inho-mogeneity using time-domain data. We use the transmitting boundary condition and the superabsorption technique in FDTD to reduce the error of scattering fields.

Key words: frequency compensation technique, time-domain Born iteration
