The Catmull Rom spline has the advantages of being intuitive, stable and flexible, without the need of reverse control vertices, etc. It is especially suitable for geometrical description of aircraft with complex shapes. Using Catmull Rom spline (G1, k = 1) The volume surface is used to geometrically model the low-scattering target and to solve the RCS contribution of the low-scattering target creep wave. Satisfactory results are obtained by comparing the calculated results with the experimental ones
