In the source region, numerical simulation usually has a bad result. So, a two-dimension point-source FDTD simulation has been completed in this paper. By analyzing the data nearby the source, some results are gained. In the source region, for its own characteristic of FDTD, reflect waves’ reaching time doesn’t agree with its expectation in theory. But the data can be corrected by counter deduction. As an application, a level interface inversion is done by using the corrected data and a good result is obtained.
