Abstract : Manmade objects embedded in inhomogeneous media such as soils, building materials, and atmospheric layers may be detected by radar-like systems. The report reviews the system requirements and examines the role polarization phenomena can play in meeting these requirements. The scattering properties of potential targets and other disturbances in the medium as well as surface reflections and attenuation effects are taken into consideration. Rigorous equations describing the depolarized echo of radar reflectors as a function of their physical shape and the polarizational state of the incident wave are derived. The scattering theory of G. MIE is extended to include dissipative media and to permit the computation of the radar cross section of spheres for any combination of complex material constants. (Modified author abstract)
