(Note that the object is just a thin shell; it does not occupy the interior of the hemisphere.) We write the hemisphere as r ( ϕ, θ) = cos θ sin ϕ, sin θ sin ϕ, cos ϕ ... WebThe small fluctuation of the RCS in Figure 5 depends on the geometric precision of the CP cells at the cylinder surface, as shown in Figure 3, such as the path length and the integral area. This implies that in order to avoid such minor issues, the CP cell model of the curved surfaces must be meticulously designed and implemented.
