Polarization filtering enhancement of buried landmine

Here the optimum polarization of antenna for buried landmines detection in soil surface clutter is investigated theoretically to enhance radar target back scattered power. An expression of the Mueller matrix from this fractal surface is obtained. The optimum polarization to reduce clutter is given. Then, the variations are found of power density of buried landmines with polarization state, and the optimum polarization is given to increase power density. In the end, the paper researches the polarization filtering enhancement of buried landmines in soil surface clutter.
