This article gives the definition of miss distance.The mathematic model in one dimension of miss distance of small caliber AA-Guns virtue fire is established.The statistic property of miss distance is analyzed,and the optimal estimation equation of correcting data based on Bayes estimation theory is deduced,and the analysis result is given.Miss distance is a kind of discrete stochastic sequence.Any special miss distance sequence can be expressed as one kind ecdysised Markov sequence.The optimization estimate of miss distance state is that the optimization filter estimate(k/k) is given by prior informant of observation output ｛x(k);k=0,1,2,…｝,minimizes the variance of estimate error.So the fire precision of AA-Guns is improved greatley.
