摘要

Positioning 3-D targets buried in layered medium with electromagnetic waves has widespread applications, such as the detection of land mines. Most of the current electromagnetic inverse methods need to know the preknowledge of the dielectric properties for layered background medium, in order to accurately reconstruct concealed targets. However, this condition is hardly satisfied in real problems. In this letter, an electromagnetic inverse scattering series method (EISSM) is developed and derived for positioning 3-D targets buried in two-layered medium. The prominent advantage of the proposed method is that it does not need any prior information about the dielectric properties of the layered medium. The position error predicted by the EISSM is analyzed and discussed. Compared with the commonly used time-reversal-mirror technique, numerical simulations show that the EISSM is capable of positioning the target buried in two-layer medium with less error.
