基于稳态遗传算法的间歇式覆盖天基雷达星座优化设计

针对天基雷达星座的构型优化设计,建立了能够反映星座重要工作性能的单双基地间歇式覆盖模型、星间链路模型、双基地雷达的动目标检测模型,得到了低轨道卫星星座星间链路判断准则,给出了统计评价特性和综合评估指标体系。在此基础上,建立星座设计的优化模型,采用基于可行解搜索法的协同演化遗传算法并融入稳态遗传进化策略,有效地处理带有复杂计算的目标函数和约束条件的星座优化问题,计算分析实例表明利用该方法进行星座设计是非常有效的。

Optimization Design of Discontinuous Coverage Space-based Radar Constellations via Steady State Genetic Algorithm

A steady state genetic algorithm which can deal with several criterion functions was applied to the design optimization of Space Based Radar(SBR) satellite constellations.The discontinuous coverage model,inter-satellite links geometry model and bistatic moving target detection geometry model,which can describe the working properties of the SBR constellations,were developed.Then,the statistic evaluation and comprehensive evaluation indices were put forward,and the design optimization model was established.According to the particularities of this problem,steady state co-evolutionary genetic algorithm on the basis of searching in feasible solutions was used to deal with the design optimization problem.Finally,several design examples were presented,showing that the method is effective.
