Abstract

The invention relates to an integrated support for RCS testing of a large-mass low-scattering target and its application. The integrated support is made of wood with the following properties: the air-dry density is (100‑250) kg / m 3 ; Air-dry hardness is (400-800) JH James hardness; moisture content is 8%-15%; and relative dielectric constant is not more than 1.05. Wood with specific properties (air-dry density of (100-250) kg / m 3 Air-dry hardness is (400-800) JH Jen's hardness; moisture content is 8%-15%; and relative dielectric constant is not more than 1.05) as raw material processing support, the support that adopts above-mentioned wood as material to make has more than foam support. Higher hardness and rigidity, higher dimensional stability than foam brackets, and much smaller stress deformation than foam brackets, suitable for high-frequency RCS tests that are sensitive to subtle deformations such as Ku-band, K-band, and Ka-band.

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...
