英文摘要：
This paper studies the similarity degree measuring method for motion reconstruction of cooperative spacecrafts. The variables＇ scaling factors of orbit and attitude of motion reconstruction of cooperative spacecratfs, and the factors for establishing similarity degree of a simulation system are given respectively. Then, the assessment index model of similarity degree for motion reconstruction is established, the similarity elements and its characteristic variables are determined, the construction method of weights of similarity degree and the computational method of similarity value of similarity characteristic variable are given, and on these basis, the measurement equation of similarity degree are proposed. At last, the similarity degree analysis is given for the ground experiment system of the final approach phase of spacecraft rendezvous and docking in circular orbit. The simulation results show that the proposed analysis method has guiding significance for selection and improvement of experiment scheme.
