WebAssume that the RCS of a conducting sphere as a function of radar frequency can be modelled piecewise by two regions (a) an optical region for a/ 0.1, where σ=찌, and (b) a Rayleigh regine for a仄< 0.1, where σ-α/λ4. a is the radius of the sphere and 2 is the wavelength. (a) Assuming continuity in values from region to region. find a. WebSep 16, 2014 · It has been shown that the radar cross section (RCS) calculations can be done in Rayleigh, Mie, and optical regions by the 2-D FDTD simulation. Finally, the RCS …
WebIn the Rayleigh region, the circumference (or size) of the PEC sphere is small relative to the wavelength of the transmitted signal (2 π a λ ≪ 1). As a result, in the Rayleigh region, the theoretical RCS of the ideal PEC sphere can be approximated as 9 λ 2 4 π (k a) 6. Webangle. This gives rise to deep null in the bi-static radar scattering cross-section (RCS)6 of a PEC sphere as illustrated in Figure 34.4. Figure 34.4: RCS (radar scattering cross section) …

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.
