Abstract : Approximate methods based on the pertinent scattering mechanisms are given for determining the radar cross sections of plasma clad bodies. A superposition principle is used combining the scattered fields from the sheath alone and from a modified metallic body. Appropriate modification of the scattered fields of the modified metallic ody are discussed with respect to the physical phenomena involved. Approximate radar cross sections of spherical bodies clad in concentric spherical sheaths are compared with the exact multip le expan i n solutions giving excellent agree ent for all sizes and dielectric constants except for small restricted regions. An approximate method based on macroscopic properties is given for determining the radar cross section of dielectric bodies. This method is superior in accuracy, simplicity, and range of validity to previous methods. (Author)
