The inverse of the parameters of underground targets is still highly in expectation in Ground Penetrating Radar(GPR) applications. In this paper, the fdtd method and time-domain optimization algorithm have been used to reconstruct the permittivities of underground multiple targets. An iterative optimization algorithm has been put forward. The forward scattering data are also calculated by 2.5d-fdtd algorithm in order to better simulate the practical GPR situation. The relationship between the convergent rates of the inverse algorithm and the initialization values are studied.
