Webradiation, when impinged at normal incidence. The conceptual definition of RCS includes the fact that not all of the radiated energy falls on the target. A target‘s RCS is most easily visualized as the product of three factors: projected cross section, reflectivity, directivity. Reflectivity is defined WebThe RCS varies with the incident angles (also known as aspect angles). Aspect-dependent RCS patterns can be measured or modeled just as you would antenna radiation patterns. The result of such measurements or models is a table of RCS values as a function of azimuth and elevation angles in the target's local coordinate system.
