A modified LSM method for buried objects in a layered medium

A modified Linear Sampling Method (LSM) is presented to detect buried object in layered medium. Cauchy Data is exploited to reformulate conventional LSM method in terms of homogeneous Green´s function instead of the layered medium Green´s function. As a resul, a modified LSM can be effectively applied to detect the object buried in non-smooth layered medium. Numerical examples are presented to demonstrate the feasibility of the method.
