In this article we perform a numerical study of the generalization of parabolic non-diffraction beams of two orders formed from an analytically given distribution of the ring spatial spectrum. The formation and propagation of non-diffraction parabolic beams are simulated using the Fourier transform and the Fresnel transform. The influence of the radius and width of the circular spatial spectrum on the non-diffraction properties of the beams, as well as the nature of the symmetry of the transverse beam patterns depending on the orders of the beam are researched.
