(telecommunications, aviation) A measure of the detectability of an object by radar.
A normalized log–log plot of the radar cross section of a metallic sphere as a function of the radiation frequency. For cases in which the circumference of the sphere is less than three-fourths of the wavelength, the radar cross section is approximately proportional to ƒ4 (ƒ=the frequency of radiation). For cases in which the circumference of the sphere is greater than 20 wavelengths, the radar cross section is approximately the same as the physical cross section of the sphere. This plot is known as Mie scattering.
(telecommunications, aviation) A measure of the detectability of an object by radar.
A typical RCS diagram (using the A-26 Invader as the scattering object). The diagram is a polar plot of the RCS as a function of angle, with the image of the plane in the center helping to relate the angles in the diagram to physical features of the scattering object
(telecommunications, aviation) A measure of the detectability of an object by radar.
The B-2 Spirit was one of the first aircraft to successfully become 'invisible' to radar.
