WebApr 11, 2024 · Based on that, the NEBO SVU should be able to detect an F-35, which has an estimated RCS of 0.25m² in the VHF band, at a range of around 152 kilometers. And therefore, the destruction of Nebo SVU by the Ukrainian forces is significant, as it represents a very advanced ground-based early warning radar system for the Russian armed forces. http://helitavia.com/skolnik/Skolnik_chapter_11.pdf
Webeffect is the presence of fluctuations located in the Rayleigh region. Theses RCS fluctuations imply the far-field approximation cannot be considered in this case. Moreover, for large targets, the measured RCS is mostly either in the Rayleigh region or the Fresnel region where the value of the RCS is not constant. WebSep 23, 2024 · The y-axis is the RCS relative to the projected area of the sphere i.e. σ/(πR 2). The asymptotes are σ/(πR 2) = 9 (f rel) 4 in the low frequency (Rayleigh) region (λ > 2πR) , and σ/(πR 2) = 1 in the high frequency (optical) limit (λ << R).
Websphere, the incident radiation is uniformly scattered in all directions (Isotropic scattering) and the RCS is given as, σπ=a2 When the wavelength is not small compared with the sphere radius, the calculation is much more complicated. This region where the wavelength is not small compared to the radius is called the Mie region or resonance region.
