Abstract: As it is difficult to carry on a large number of test to analyze the weapon system at present, classical statistical method is difficult to satisfy the demands, this paper evaluates the fire concentration reliability of rocket under the condition of small sample. According to the ground simulation environment and flight test information, it utilizes Bernoulli distribution to confirm the distribution of fire concentration reliability of rocket, and uses the computer to deal with number value. In the case of not reducing test requirements, compared with classical method, the small sample theory has reduced the number of flight test by a large margin.
