英文摘要	With the expansion of the human's actibity in exploring,utilizing the outer space,protecting space environment have become the most sighificant task in space navigation.Since the neglect of the space debris environment in the past century,the total number of orbital space debris increases rapidly,which leads to an unaccepable large risk of collision to spacecraft.Space Debris Collision Avoidance(SDCA)is the only strategy to reduce the risk of collision,when dimension of space debris lager than 10cm.The decision whether the avoiding maneuver is necessary depends on the analysis of conjunction,the rigorous calculation and assessment of collision risk between space-craft and debris and compare to the collision criterion.This paper initially introduces the flow of the Space Debris collision avoidance system(SDCAS),with comparing of the two kinds of warning criterion,the main topic on method of collision probability is evoked.collision probability is a new type of warning criterion,which not only takes the miss distance into consideration,but regards all the geometrical parameters.Eventually,with the detailed analysis,the effect of the covariance or uncertainty to the collision probability has been drawn to the surface,whoch plays an indispensable role in measuring the risk of collision.the attitude of the error ellipse which is constructed by the role in measuring the risk of collision.the atttude of the error ellipse which is constructed by the covariance has also dffect the result of collision probability.Based on the analysis of covariance,the method of sollision probability posts many advantages to the Box method.Especially,the rate of false warning has been decreased dramdtically.
