The invention discloses a low-scattering carrier for detecting forward traveling waves of a wave-absorbing material, and belongs to the field of low-scattering carrier appearance design, and the low-scattering carrier comprises a carrier body which is composed of an upper surface, a lower surface and two side surfaces; the shapes of the upper surface and the lower surface are respectively a triangle, a special trapezoid and a rectangle which are seamlessly connected in sequence; the two waists of the special trapezoid are convex arcs, and the two side edges of the triangle are in transition connection with the corresponding side edges of the rectangle through the corresponding convex arcs, so that the triangle, the special trapezoid and the rectangle form a concave second-order curved surface; vertexes formed by two side edges of a triangle in the upper surface and the lower surface are jointly used as a forward tip of the carrier body, and rectangular bottom edges of the upper surface and the lower surface are seamlessly overlapped; a to-be-tested wave-absorbing material is arranged on the rectangular surfaces of the upper surface and the lower surface. According to the method, the accuracy of evaluating the RCS reduction performance of the forward traveling wave of the wave-absorbing material at different pitch angles can be improved.
