%X A novel method, time-domain variational iterative method(TVIM), for microwave imaging of two-dimensional lossless electromagnetic target buried in half space using time-domain scattering data is presented in this paper. It is an iterative method derived using volume equivalence principle, variation principle and Fourier transform. The direct problem is solved by finite-difference time-domain(FDTD) method and the inverse problem is solved iteratively. Some typical results are given to show its performance, such as converging property, ability to invert arbitrary targets, tolerance of random noise, etc. Comparision with the former methods is also done. Those factors which make TVIM performs better are also investigated.
