摘　　要：针对在轨拦截器的特点,建立了远程导引段多脉冲轨道机动模型和基于比例导引的末段拦截模型。以能量-脱靶量为指标构造了多目标轨道转移优化模型,基于构造编码方式、克隆操作、免疫基因操作及克隆选择等操作,设计了适于解轨道转移优化模型的人工免疫克隆算法(AICA)。仿真结果表明所建模型可有效解决以能量-脱靶量为指标的轨道优化问题。According to the characteristic of orbit interception, the model of orbital-maneuver in long-range by multi-pulse and interception in short-range by extended proportional navigation guidance law was established in this paper. The multi-object model of optimize orbital transformation based on fuel cost and miss distance was proposed. The immune clone algorithm which was adopted to optimal orbital transformation based on encoding mode, cloning operation, immunity genetic operation, cloning selection operation were constructed. The simulation results showed that the model designed could solve the optimizing orbital transformation based on fuel cost and miss distance effectively.
