At present, if a compact range RCS test imaging technology is adopted for testing local defects of scattering performance of a low-RCS target body, the resolution is in a decimeter level; if a traditional planar near-field test is adopted, only test evaluation in a two-dimensional plane can be completed. In order to overcome the defects in the prior art, the invention provides a near-field RCS (radar cross section) evaluation device and evaluation method based on a mechanical arm, performance defect parts are effectively provided by testing scattering performance of each area on the surface of a two-dimensional or three-dimensional target body, and improvement guidance of the target body is completed. The invention aims to realize high-precision, high-resolution and high-dynamic automatic three-dimensional near-field RCS test, effectively improve the development efficiency of a low-RCS target body, promote the development of a component-level stealth technology, and provide powerful support for the improvemen
