| Abstract: | By considering the credibility of the prior information, a new Bayesian estimation algorithm is studied, and the estimation of normal distribution parameters is provided. Taking the estimation of the dispersion of the missile falling points as an example, the conclusion is drawn that by considering the credibility of the prior information, the new algorithm of Bayesian estimation is obviously improved,that is, it is of a better credibility. |

| Keywords: | Bayesian estimation prior information confidence le vel dispersion of the missile falling points |
