Abstract

The invention relates to a low-scattering carrier for darkroom background level evaluation test, the low-scattering carrier is in a drop shape, the low-scattering carrier is provided with a head part and a tail part which is relatively sharp relative to the head part, and the included angle [alpha] of the tail part is 10-60 degrees; the carrier is provided with an upper surface and a lower surface; the upper surface is a curved surface protruding upwards; the lower surface is a plane, and a circular connector used for being fixedly connected with a rotating top is designed in the middle of the lower surface; and the upper surface is seamlessly connected with the lower surface. According to the integrated structural design of the evaluation equipment and the support interface, the equipment and the support rotating top can be smoothly connected, the curvature of the interface is consistent, no obvious order difference or gap exists, the screw is sealed by an aluminum foil or a conductive adhesive, scattering interference of the bottom edge and the inner cavity structure of the equipment can be eliminated, which is crucial for obtaining the accuracy of darkroom background level response in a test; and after wide popularization and application, good economic benefits and social benefits can be generated.

Description

technical field [0001] The invention relates to the technical field of electromagnetic scattering characteristic measurement, in particular to a low-scattering carrier used for the evaluation test of the background level in a dark room. Background technique [0002] The RCS measurement in the anechoic room must first measure the empty field to obtain the background level response. When the foam support is supported, it is necessary to load the low-scattering evaluation equipment to obtain the background scattering level under the target test state. When the low-scattering metal support is supported, because the top of the support There is a two-dimensional turntable, if not effectively shielded, the background scattering test will not be possible. Therefore, a low-scattering carrier for measuring background level response is needed, which avoids specular reflection and edge diffraction and can better suppress traveling wave scattering, so that it can be measured and evaluate...
