According to the movement characteristic of the space targets and the orderliness of feature changing, the reaction time of track initial can be changed by recognizing the targets of different features. The track can be initially successful because it satisfies the requirement of position, feature and pruning. The experiment result indicates that the proposed method overcomes the disadvantage of traditional gliding windows method, which is easy to lose objects under the heavy clutter circumstance. And the result also shows that the method promotes the precision of measurement. Key words : Track initial; Multiple feature association; Target dete
