Abstract：A system effectiveness evaluation index screening method based on grey principal component analysis was proposed to solve the limited sample size and irregular sample distribution in system effectiveness evaluation. The geometric similarity of the serial curve evaluated the correlation of the evaluation index with combat effectiveness. The association between combat effectiveness and evaluation index was quantified by the correlation degree and screening key index in system effectiveness evaluation. This method can verify the feasibility of missile defence.
