针对粒子群算法跟踪空中目标的缺点,提出随机占优精英裂变算法.首先对父体大权值粒子裂变,形成子代个体空间,覆盖小权值粒子；接着采用精英策略,计算个体在选择过程中被选中的概率,使大部分较优个体参与进化,用极小欧几里德距离计算拥挤距离；然后采用分布函数来确定采样数据的随机占优关系；最后给出了空中目标运动模型.实验仿真表明,滤波轨迹接近空中运动目标的轨迹,在整个观测区域内具有很好的跟踪效果,位置误差标准值小.%Considering the disadvantages of particle swarm optimization algorithm in aerial target tracking, stochastic dominance elite fission algorithm was proposed. After the fission of the parent body weight value particle, individual space was formed, which covered with small weight particle. Then, the elitist strategy was adopted for calculating the probability of an individual being selected, made the most of fine individuals participate in evolution. The crowding distance was calculated out with minimum Euclidean distance, and the distribution function was used to determine the sampling data of stochastic dominance relation. Finally, the aerial target motion model was given. The experimental simulation showed that: 1 ) the filtering trajectoriy is approximate to the aerial target moving trajectory; and 2) the tracking effect is satisfactory during the entire observation area.
