Design of 3D Low-scattering Carrier with Controllable Parameters

Radar cross section (RCS) measurements using a low-scattering metal support require the background response of the test site, and the low-scattering carrier is used to wrap the turntable at the top of the support, thus reducing the scattering of the turntable. Typically, the low-scattering carrier consists of parameterized surfaces and provides sufficient internal space to accommodate the turntable. Considering the low-scattering characteristics and spatial size limitations, this paper designs a parameter-controlled three-dimensional low-scattering model. The model's back-scattering performance in the P-band was calculated using the method of moments, which showed lower RCS values compared to typical ogival body. The simulation results demonstrate that the design methodology of the low-scattering carrier presented in this paper has considerable application value.
