Abstract : Considerable work has been accomplished in the area of analyzing the reflection and refraction of plane electromagnetic waves at a plane surface boundary, where the electrical parameters of the mediums under investigation are constants. In the area of Military Geographic Intelligence there exists a need to determine terrain surface and subsurface phenomena by the use of remote sensors. There is also a need to understand the consequence of nonhomogeneous soil mediums on the return energy going to a remote sensor such as a side looking airborne radar system. These needs can be fulfilled efficiently only when an understanding of the propagation and reflection of electromagnetic waves from natural terrain surfaces has been achieved. The understanding can be aided by solving the vector wave equation for the case where the soil conductivity and dielectric constant are functions of soil depth. (Author)
