Abstract :
Summary form only given. An attempt is made to develop a unified methodology for the computation of bistatic and monostatic RCSs (radar cross sections) of conducting/dielectric objects situated over a layered medium. The analysis is quite different if the layered medium is finite as opposed to an infinite dielectric layer. The surface equivalence principle along with the conventional integral equation technique is utilized to convert the physics to a mathematical entity. The integral equations are solved utilizing the conventional method of moments. For the infinite layered structures, the Sommerfeld Green´s functions are utilized to take into account the effect of the various lossless/lossy dielectric media. For finite layered media, one utilizes the equivalence principle and replaces the layers by surface equivalent electric and magnetic currents. As part of the solution procedure one also has to solve for these additional equivalent surface electric and magnetic currents.<>
