Webreflectivity. The radar cross section of an object is proportional to the far-field ratio of reflected to incident power density, that is: Typical Values of RCS for Ships. Introduction. RCS of ship depends on overall size and Gross/displacement tonnage of ship. Typical values for ships are known and described below: WebThe RCS is the projected area of a metal sphere that is large compared with the wavelength and that, if substituted for the object, would scatter identically the same power back to the radar. However, the RCS of all but the simplest scatterers fluctuates greatly with the orientation of the object, so the notion of an equivalent sphere is not very useful. WebThe conceptual definition of RCS includes the fact that not all of the radiated energy falls on the target. A target’s RCS ( F) is most easily visualized as the product of three factors: F = … flagship schemes of goi
