Low-scattering metal bracket system for remote calibration during RCS measurement process

Disclosed is a low-scattering metal bracket system for the remote calibration during the RCS measurement process. The system comprises a calibration object, a calibration bracket and a moving unit. According to the technical scheme of the invention, a low-scattering metal bracket is adopted as a calibration bracket. On the premise that a test position is kept unchanged, the echo of a test target is not influenced at all. Therefore, the background changing condition can be monitored in real time. The influence of the external environment on the stability of the calibration bracket can be avoided. Meanwhile, the environment adaptability of the calibration bracket, and the accuracy and the precision of measurement results are improved. Through arranging the calibration object on the calibration bracket, the remote calibration purpose is realized. The problem that due to the un-realization of remote calibration, a to-be-tested object and a test standard body need to be replaced alternately so as to cause the low installation efficiency and poor test accuracy can be solved.
