A new method of calculating generalized correlation coefficient for reliability analysis of missile

According to the mechanism of identification of internal disturbance factors of missiles and the effect analysis on their performance and reliability, the correlation among these factors was analyzed. The problem of the calculation of correlation between two factors was solved by defining effect function and considering the correlation between two effect functions as the correlation between two factors. A new generalized correlation coefficient was proposed to describe the correlation between two variables quantitatively, and the superiority of this method was shown through analysis and comparison. At the end of this paper, the steps of reliability calculation based on generalized correlation coefficient were developed. And then an example is used to valid the method.
