Research on G-brewster of the composite model of target on rough surface

Brewster phenomenon is that the value of the specific angel of incidence for which the Fresnel reflection factor for TM light is null. It also affects the multipath effect of target on rough surface. The composite model of target on rough surface is built up, and PO-MEC is used to calculate the scattering field of the target, which is meshed. The multipath effect is studied on Four Path Model with the coefficient of rough surface. The G-Brewster is brought up on the basis. The condition of its existence is studied, and the elements of the composite model are taken in account. The characteristics of G-Brewster are shown up. The conclusion on G-Brewster is meaningful to overcome multipath interference.
