However, in the optic region, the RCS value (σ s) of an isotropic sphere with a diameter of r can be determined based on its geometric cross-section [6,7], which is
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. 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.
