WebWhat are the parts of RCS in radar? 10.4. The RCS of a simple conducting sphere as a function of the normalized circumference (2πa/λ, where a is the radius of the sphere and λ is the wavelength) is shown in Figure 10.1. The RCS of this figure can be divided into the Rayleigh region, the Mie or the resonance region, and the optical region.
