Abstract

The invention discloses a low-scattering foam support for target radar scattering characteristic testing, which belongs to the technical field of RCS (radar cross section) testing, comprises a foam supporting platform, and is characterized by further comprising a foam supporting seat, a first foam supporting body, a second foam supporting body and a third foam supporting body, the first foam supporting body comprises a first large supporting body and a first small supporting body detachably connected to the first large supporting body, the second foam supporting body comprises two second supporting blocks which are detachably connected, the two second supporting blocks are symmetrically arranged along the horizontal line, the third foam supporting body comprises two third supporting blocks which are detachably connected, and the two third supporting blocks are symmetrically arranged along the horizontal line. The two third supporting blocks are symmetrically arranged along the horizontal line, and the first large supporting body is located above the foam supporting base and connected with the foam supporting base in a mortise and tenon mode. The erecting height of the foam support can be adjusted, leveling and positioning of the support can be achieved, the low scattering characteristic of the support is guaranteed, and the testing effect is improved.

Description

technical field [0001] The invention relates to the technical field of RCS testing, in particular to a low-scattering foam support used for the test of target radar scattering characteristics. Background technique [0002] RCS, that is, radar scattering cross section, is a physical quantity that characterizes the scattering of a target to incident radar waves, and is the core indicator in target stealth and target detection. Conventional RCS testing methods include far-field testing, tight-field testing and near-field testing. No matter which testing method is used, high requirements are placed on the way the target is supported and erected. The bracket should not only meet the intensity requirements, but also ensure that its scattering intensity is low and does not affect the test background. [0003] For large-scale targets, the erection is usually completed in the form of "support rod + hanging". This method requires high control accuracy and can only be aimed at a speci...
