Aimed at the prime state problem about dynamic object position in the field, the statistical method is used to analyze distributing rule on dynamic object area position. Through studying the distributing theory on the dynamic object position, measuring the coordinate date of dynamic object and using statistical method such as hypotheses on normal distribution, hypotheses on exponential distribution, hypotheses on Raleigh distribution and hypotheses on the parameter, the distributing rule on dynamic object position is found. Based on the result of discussing each one test significance level, the distributing of dynamic object position can be is seen as hypotheses on exponential distribution in the level of significance.
