WebOPTICAL / MIE / RAYLEIGH REGIONS. Figure 7 shows the different regions applicable for computing the RCS of a sphere. The optical region (“far field” counterpart) rules apply when 2Br/λ > 10. In this region, the RCS of a sphere is independent of frequency. Here, the RCS of a sphere, σ = π r2. WebWhat are the parts of RCS in radar? 10.4. The RCS of a simple conducting sphere as a function of the normalized circumference (2πa/λ, where a is the radius of the sphere and λ is the wavelength) is shown in Figure 10.1. The RCS of this figure can be divided into the Rayleigh region, the Mie or the resonance region, and the optical region. cvs vaccine clinic covid

WebPROBLEM. In Section 2.2.5 of the text, it was demonstrated that the radar cross section (RCS) of a target modeled as a set of “many” individual point scatterers was a sufficiently complex function of aspect angle (or frequency) that it could be modeled as a random variable; and further that the law of large numbers suggests that one assume an … Webinto three regions, named Rayleigh region, resonance region and optical school district. 1. The characteristic of Rayleigh region is that the working wavelength is larger than the target characteristic size, generally taking the range of ka<0.5.
