Radar cross sections of dielectric or plasma coated conducting spheres and circular cylinders

摘要: Radar cross sections for a variety of spherical and cylindrical scatterers having homogeneous dielectric or plasma shells are obtained by using both the exact boundary value solutions approximate, semi-empirical methods based on physical principles. The is assumed to have macroscopic properties lossless with permittivity less than that free space. A superposition approximation radar section coated conducting body considering scattered field be phasor sum two principal components, air-dielectric interface an equivalent which differs from actual because lens action shell. This yields very good agreement clad radii in Rayleigh region resonant region, bistatic scattering as well backscatter. echo area sphere nonconcentric shell calculated means excellent experimental measurements, thus demonstrating validity this method case solution cannot obtained.
