Abstract

The invention relates to an integrated bracket for radar cross-section (RCS) test of a large-mass low-scattering target and application of the integrated bracket. The integrated bracket is made of wood with the following properties: the air-dry density is (100-250) kg/m<3>, the air dry hardness is (400-800) Janka hardness (JH), the water content is 8%-15%, and the relative permittivity is not greater than 1.05. The wood with the specific properties (the air-dry density is 100-250 kg/m<3>, the air dry hardness is (400-800) JH, the water content is 8%-15%,and the relative permittivity is not greater than 1.05) is adopted as a raw material to machine the bracket, compared with a foam bracket, the bracket made of the wood as the material has higher hardness and rigidity, the size stability ishigher than that of the foam bracket, the stress deformation is much smaller than that of the foam bracket, and the integrated bracket is suitable for high-frequency-band RCS tests, sensitive to finedeformation, of a Ku waveband, a K waveband, a Ka waveband and the like.

Description

technical field [0001] The invention relates to the technical field of RCS testing, in particular to an integrated support for RCS testing of large-mass low-scattering targets and its application. Background technique [0002] Western developed countries represented by the United States and Asian neighbors represented by Japan attach great importance to the research and development of stealth technology. The competition in the field of stealth is becoming increasingly fierce, and new technologies and ideas are emerging in an endless stream. With the continuous development of stealth technology, the RCS (Radar cross-section) value of the target is getting lower and lower, making the detection of the target more and more difficult. difficulty. In order to clearly understand the electromagnetic scattering characteristics of different targets in various attitudes and different electromagnetic environments, grasp the corresponding target electromagnetic scattering characteristic...
