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 optimizationalgorithm 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.
